DSLR Astrophotography

[vapid goblet]

i visited b5 it was soooooooooooo dark

[candid walrus]

Nice! what did you shoot? and what bortle are you normally?

i thought you was like B5-6

[tepid root]

B5 is dark?..

[candid walrus]

For some XD

[tepid root]

Is it actual b5 or is it one of those secret b5’s that are actually b2’s but light pollution map hasn’t updated as only recently the entire city near by you burnt down and all light sources within a 100km radius exploded

[candid walrus]

Nah honestly B5 compared to B7 is huge! i live at B5, but went to a place that was B7, could barely see any stars ngl

compared to what im used to

[tepid root]

I usually live at b5 and I’m at b7 now

Even with the moon out I could see quite a bit of stars

Maybe even the slightest of mw or the Magellanic Clouds

[candid walrus]

Maybe you just got the god tier eyesight XD

[tepid root]

I could see I believe the tiniest bit of smc and lmc

I could see 47 tucanae the bright cluster

[candid walrus]

I can see the mw faintly at home if seeing is good, but at B7 there is literally no way lol you sure it wasnt B2 called B7? XD

[tepid root]

I’ve been to b2, I flashed a torch in my eyes for 10s and instantly looked and saw the entire mw arch in full details brighter then some clouds at b5

I could see lots of small nebulae just with my eyes without dark adaption

[candid walrus]

Damn, never been below B4, mainly because its a 8hour drive to B2 but still XD man thatd be sick, but if you saw mw in B7 then that aint B7 XD

[tepid root]

B2 is like living in a dream

[vapid goblet]

high b7

[tepid root]

It’s like constantly seeing a mw panorama with your eyes in mono

[vapid goblet]

B5 I could see the milky way for the first time

[tepid root]

That’s what I’m at now with the moon up in b7

[vapid goblet]

even with the moon

[tepid root]

How much percanteage

[vapid goblet]

It was like 50%

last night

[tepid root]

I have seen the mw before in b5

[candid walrus]

Same

[tepid root]

B5 mw is not comparable to b2 mw

[candid walrus]

Yeah definitely

[tepid root]

I’ve been to most bortles now the difference Is quite astounding

[vapid goblet]

b5 is the lowest ive ever been

and its amazing

[tepid root]

How much do you see

[vapid goblet]

i saw so many extra stars compared to b7 I struggled to recognition constellations

[tepid root]

Any mw?

[vapid goblet]

if I looked straight at the milky way it did look like a streak but averted vision began to show some kind of structure

most structure is visible in cygnus

[tepid root]

It takes a min for me to see the mw

I don’t instantly see it in b5 sadly

[vapid goblet]

The more I looked, the more that was visible

[tepid root]

But after a bit I can see the mw core and some southern mw like near carina

[vapid goblet]

Dark adaption is essential

Oh yeah milky way core is invisible from my spot in the northern hemisphere

[tepid root]

I’ve always wanted to see Cygnus

I always thought it would be like super bright

[vapid goblet]

Orion is brighter

[tepid root]

Yeah but Orion you don’t got as much

I can see Orion naked eye, you can prob see it naked eye in b9

[vapid goblet]

orion also doesnt rise much here

eh well it kinda does

the belt only gets to 40 degrees though

[noble dagger]

yeah, thats true

[fading osprey]

Nah Cygnus is anticlimactic

It’s basically just Vela and really faint milky way

[noble dagger]

Sagittarius is better

you can see so many DSOs

like eagle, swan, m24, some clusters, lagoon, trifid and co

[tepid root]

Yeah they are all cool i liked shooting all of them

They are all easy fun for the whole family targets too great for stock if you want a nebulae visible but then you realise that there is a crap ton of invisible ha that makes you go insane for a while thinking about temptations in buying an astro cam.

[noble dagger]

but its a way different experience seeing them with the naked eye

[tepid root]

Yep def

I’ve seen the core so brightly before it’s very beautiful

In b5 it’s visible but like still a lil dim

[noble dagger]

go to a b3 sky or less. i can be so happy to be partially living in one (the night sky there is one of the most beautiful things i know)

[tepid root]

I’ve been to b2 before and the mw core looked super bright and I could see all the nebula

[noble dagger]

life in the city just sucks...

[twin pawn]

The map shows I'm in bortle 5 but either my eyesight is ass or it's actually bortle 6.

[vapid goblet]

apparently looking at a bright light for even a short time ruins dark adaption but i found thats not the case from my experience

it took staring at bright lights for longer periods to lose dark adaption

[noble dagger]

Wdym?

[twin pawn]

DSLR gang gen chat

[hard fossil]

Use spot stars on photopills

[craggy lark]

Hi, I can't decide between these two old camera lenses.
The first one is a Pentacon 135mm 2.8 .
The other one is a Carl Zeiss Sonnar 135mm 3.5 .

I'm wondering which one is better for astrophotography, and which one has less Cromatic Aberration

[twin pawn]

I would imagine Zeiss glass would be better, but I'm not too familiar with vintage glass as far as which lenses are the sharpest.

[modern sluice]

Could go either way. One thing about vintage lenses is that the current condition can vary widely even between examples of the same make and model.

so hard to say without testing them

[amber girder]

Shooting the solar eclipse

[noble dagger]

Is it day for you rn?

[amber girder]

Yeah man

It was 5pm at that time

[noble dagger]

Oh wow, it was 10 pm for me

[lethal pollen]

M33 2h30

Canon EOS 50D with Quattro 150p

severely undersampled because pixel scale sucks on the 50D - its 4.69 micrometers on an aps-c sensor

Gotta buy a proper astro camera soon

[untold sinew]

Wow I’m glad people still use this

[twin pawn]

Try the 5.2 um pixels on my 450D lol

[lethal pollen]

Would 2x drizzle when stacking improve anything in this image?

[twin pawn]

My internet is crap atm so I couldnt load the whole image but it looks like your better sampled than me and drizzling my data doesn't improve anything enough to be worth it.

So your fine most likely

[hazy venture]

First astro photo M31 with abt 30min and no calibration frames

[twin pawn]

Just finished my two panel mosaic on the Heart and Soul. Both sets of data have been absolute surprises as far as quality.

https://discord.com/channels/794642864218439681/1164022265709604887

[lethal pollen]

Wow thats beautiful and so clean, whats your pixel scale in that image? its very sharp

[twin pawn]

Thank you! That image is around 3.8 arcs/p andy 450D has 5.2 um pixels.

[noble dagger]

That is 3.8 arcs/pixel?

[twin pawn]

Maybe closer to 4.3, which iirc is what stellarium/telescopius states.

Around 4 regardless

I think it's closer to 3.8 with the 1x flattener.

[quiet solar]

Bortle 8,London,Nikon D780, 8h20m cose of Bortle.. Sigma 150-600mm Sport no Astro stuff

[quiet solar]

Looks like dew. Try lens heater. Use background extraction before any other steps. Do you use lens hood? You can make it from carton box or some very cheap on Aliexpress. Also take darks and flats ~25.

[twin pawn]

Single 120" sub

Crop of course

andromeda dust details with my canon eos 7d mk ii

[twin pawn]

Oh dam

[twin pawn]

Thought I was a bortle 5 for so long, then I realized I don't see anything more than most people can in B6.

[noble dagger]

Thats even more sad

[twin pawn]

I'm still glad I'm in the middle of the spectrum and not in the heart of a city.

[noble dagger]

Yeah, also depends in which direction you're shooting, with a (maybe) different Bortle.

[twin pawn]

Yii South I have a massive light dome from an airport.

[noble dagger]

Oof, you can literally forget to shoot MW core without narrowband filters

[twin pawn]

@noble dagger 5.5hrs of broadband using my T5

Stock cam btw

This is HaRGB

The broadband is more impressive because yea the massive light dome. But it's feasible because stuff is so bright there.

[noble dagger]

The Broadband?

[twin pawn]

Yii, the top image using no filters

Broadband vs the narrowband+broadband

[noble dagger]

But what do you mean with more impressive? I think the one with Ha looks better

[tepid root]

Broadband one looks cooler

[rustic meteor]

I think he’s saying it’s more impressive considering the circumstances

[twin pawn]

Yes exactly, it's more impressive considering the conditions we were discussing

[tepid root]

Is your image untracked?

[candid walrus]

No he was using a Ioptron SGP, but he was using a stock DSLR which cut out some Ha, and wasnt using narrowband filters while in B6

[inland cypress]

not dew the problem is hes not using calibs, thats a very common lens vignetting issue

[tepid root]

why do orion never look good

[twin pawn]

Waa?

[tepid root]

I try so hard but my Orion no look good

[tepid root]

Process my Orion

[fading osprey]

How much integration time?

[tepid root]

2h

I got a better process just by doing Orion cropped

Looks cleaner

[fading osprey]

Looks about as expected for that much time from like b5 or so

What bortle are you in?

[tepid root]

B5

[fading osprey]

Yeah I mean it looks good for that amount of time then, could use a bit of star color but you shouldnt expect to get much dust around Orion’s nebula

[tepid root]

Can you try my data ?

It would mean a lot 🥺🫓🫓

[fading osprey]

Yeah I can have a go at it tomorrow. Getting kind of late for me.

[tepid root]

Ok https://drive.google.com/file/d/1QlAb0oYnugfC61l1ZGzr_emEocp8OaLT/view?usp=drivesdk

[fading osprey]

Alright thanks, I’ll try and remember to process it

[tepid root]

Yay 🥳

I got some dust I think around Orion

[twin pawn]

May be able to process it after work today, I'll see.

[tepid root]

It’s been like 14 hours at work you on the grind

[twin pawn]

Nah I was setting up my rig right after work, ended up being clear.

[tepid root]

can you procidisn now “?

🥺

[twin pawn]

Rip I don't have Photoshop on my second PC

Tomorrow tho

I may be able to take a stab at it

[tepid root]

Didn’t you get apod once

[twin pawn]

Nah lol

[tepid root]

Win 🏆

[twin pawn]

Well see lol

Not anytime soon

[fading osprey]

I’m gonna try and work on it tonight once I get home since I can’t get starnet on my school computer

I do have siril tho and did some stretching and got the colors to look good

[fading osprey]

Help I just ordered 6 canon XSIs

I’m gonna Astro modify all of them

[tepid root]

You could of prob gotten an Astro cam for the same price 🥺

[fading osprey]

Nah I’m gonna mod all of them, sell them, then maybe buy an astrocam

I’m on the Astro grind

[vapid goblet]

my guy is going for the big money

[twin pawn]

Yessir

[tepid root]

I’ll buy one off you

How much you selling them for

[fading osprey]

Alright sick

Between $150-175, I’ll determine it once I actually get them hands on and find what condition they are in

I’ll probably have them all done modification by the end of November though

[tepid root]

Wait idk if you can ship to Australia

[fading osprey]

Oof yeah we’ll see

I’m in Hawaii so it’s not that far at least

[tepid root]

If you can let me know when you finish them and I’ll see if I got the money

[fading osprey]

Btw your data actually looks pretty good

I’m just trying to get the background to look decent since there’s a bunch of weird splotches

[tepid root]

It’s not as good as my old data though this data was my old Orion data

Vs new

[fading osprey]

Still looks pretty decent though

Lots of detail in both for wide field

You even got some of Barnard’s ring in here

[short radish]

Hey guys, I was doing some research on some DSLR models for astrophotography. I liked the Fujifilm cameras because they have low noise, but apparently there is no Ascom driver for them, so I wouldn't be able to control them using NINA. Then I saw that there are some cheaper Sony models that have partial control via Nina, such as the a5000, a5100, a6000. But the website says it doesn't support liveview; How would it work for Nina? Could anyone who has any of these models here in the group show me? Can i see the previous frame coming out directly on the Nina screen or is that not possible on these older models?}

I'll probably buy an Asi294. But before I get one, I'm want to get a cheaper Sony camera to do some experiments

[fading osprey]

I don’t have any of those cameras, but your correct about NINA showing you the last frame taken as your camera should send all the photos it takes directly to it

[fading osprey]

@tepid root https://drive.google.com/file/d/109sqaYd_he8-Ib1qPDV7EKrRIu1synOX/view?usp=drive_link not my best work by any means, but I just tried to get as much data as i could out of it. Will probably reprocess and try to remove the gradient earlier on and work on the stars more

heres the unstretched one https://drive.google.com/file/d/16JiG8pliCQUzHG4EMI_iBghdCKdLwAmy/view?usp=sharing

[tepid root]

https://media.discordapp.net/attachments/794651916646350859/1166604013979050024/Screenshot_757.png?ex=654b17a7&is=6538a2a7&hm=f429534cf3eff6286aba1c8cd64104990806b58145d60f540d9e4c78174e38cc&

[fading osprey]

Woah is that the same data?

[tepid root]

This is my older data lol I tried it

Final process

[fading osprey]

Ah ok, I was afraid my processing skills severely lacked

[tepid root]

The one I sent now was from almost a year ago the one you did was from like a few weeks ago. The old one I did had more data.

You can try the old one if you want but it’s hard to process

My new one the only issue was walking noise and banding

[fading osprey]

I found the gradients to be a bit of a problem too, there's a weird dark spot between orion's nebula and the center star in his belt. Wasn't sure how to get rid of that.

[wild jasper]

Idk how I just found this

Yes I am a DSLR enjoyer

One that's untracked

[tepid root]

I want me a blue puppy

[hoary cradle]

I can pick up a Canon 450D for €50, thinking about doing a full spectrum mod on it. Currently working with a unmodded Nikon D5300. You guys think the cannon is worth the price and will deliver more nebulosity?

Posted this in general chat but maybe more for in here

[twin pawn]

450d modified is very capable. Your 5300 is way better tho.

The D5300 has a Sony IMX sensor I believe so instantly better than Canons in house architecture.

But again for €50 it's crazy for the price.

I've been using the 450d for years now.

I modified it last year.

Been going strong

Just finished some heart data with it.

[hoary cradle]

Hmm yes I thought so, maybe just for fun and practicing on modifying. Too scared to do it on my beloved 5300 yet

But in terms of pixels and sharpness I have no clue on what's better haha

[hoary cradle]

Looks promising, mind to share it?

[twin pawn]

@hoary cradle Yii I'm finishing up processing and I'll upload it afterwards

[twin pawn]

D5300 is much higher res at 24mp iirc

Smaller pixels will get finer detail

Of course considering your optics can hold up

[hoary cradle]

Looking forward to it!

[hoary cradle]

130 pds and a baadr mpcc mark III

I think the eq-5 pro im using is holding it back a bit. Only can go as far as 3 minute subs

These are my best images so far with it

Both cropped though

[twin pawn]

Guiding on the EQ5?

Also nice Pleiades!

[hoary cradle]

Also bidding for a 3200, broken glass on the lcd but therefore also €50. This one has 24mp I believe

[hoary cradle]

Yeah SVbony guiding haha, had the cheap sv105 camera from when I started imaging and bought a sv165 to use it with

Works ok..

[hoary cradle]

Thanks!

[twin pawn]

Any noticeable backlash on the EQ5?

[hoary cradle]

Just a little on the Dec, I think I was quite lucky with my eq-5

[twin pawn]

Hmm, I would imagine thats limiting you to the 3" subs you stated before?

[hoary cradle]

Yes could be, don't have a lot of experience and haven't really got the chance to Investigate it further. Also just ran a calibration once on phd2 and haven't touched it since.

Also using the 3 point polar alignment in NINA because I don't have a view on Polaris from the location I'm imaging. There are too many causes that could cause it

[twin pawn]

Has your guide cam change position at all?

After doing that calibration in PHD2?

[hoary cradle]

Not really, the screws were a bit loose last time I used it but it has not changed position on the tube

[hoary cradle]

I'm not confident about it because when I did the calibration I didn't read about it properly and had no clue what I was doing.

[twin pawn]

Yea if the cam changes rotation at all the calibration won't perform optimally as far as I know.

[hoary cradle]

Ah I see, will do a new calibration next time then

[twin pawn]

Yea try that, and it would be worth it to look into adjusting the backlash on Dec. Lots of guides online I believe.

[hoary cradle]

Yes definitely will do that too, lot of time for it now with the current weather

[hoary cradle]

Btw did you do a full spectrum mod and cooling as well?

Curious about how much cooling will affect the noise

[twin pawn]

Just Ha, I'd recommend just Ha mod as it's the easiest plus there's not much point on doing full spectrum unless you want to do infrared daytime photography.

Also yea cooling makes a huge diff. Peltier coolers that can cool sensors 20-40° C below ambient reduce noise a hell of a lot. But it is rather complex and in depth to make a peltier cool for DSLRs, atleast for me.

So I've skipped that and just make sure to get good darks and a lot of them.

Haven't had any issues with walking noise if my darks are proper.

[hoary cradle]

The easiest yeah? I thought for full spectrum you just need to remove the glass. What makes Ha easier?

For cooling I have easy access to a 3d printer so maybe I can try something out when I have the chance haha. But taking darks are easier for sure

[fading osprey]

No, full spectrum requires you to replace the filters with new custom glass

Which is like $70

[twin pawn]

Yii this too

[hoary cradle]

Oh didn't know that, but you also have to place new glass for Ha too right?

[fading osprey]

Nah Ha you just have to remove one filter and leave the other in

[hoary cradle]

Oh ok thanks for the info!

[fading osprey]

Also cooling should be fairly easy to achieve, you could probably cad something up that just slots and screws in in place of the LCD screen since once you get the LCD out there’s just a hole in the back of the camera for you

That paired with a low voltage fan, a plug to power it and a step down you should be good to go

[hoary cradle]

Yeah but maybe some kind of dust filter is nice though

[twin pawn]

Peltier is much more in depth of course

If you want simple fan cooling than yea that's actually not too bad

[fading osprey]

Well then cad some holes into the plate, and also a cover for those holes when your not using it

[hoary cradle]

Yeah true

Don't know if a simple fan is enough for cooling

[twin pawn]

Not regulated and will likely only bring it close to ambient which is still useful.

[hoary cradle]

Yep also true

[twin pawn]

For the price and time making it may be worth it.

[hoary cradle]

Well I don't even have the dslr yet so we'll see, I think I'll go for the d3200. It's on auction and still the highest bidder. Asking price is only €50 but my highest bid is 25 now

So let's hope for the best

My brother is a engineer with lots of experience in small electronics so that makes it a lot easier for me haha

[hoary cradle]

Yes definitely, peltier cooling needs an enclosed space though right?

@twin pawn looked you up and added you on IG man, great images

[twin pawn]

Just saw it

Thanks man!

[twin pawn]

Yup, many people make a styrofoam shroud for the cam

Seems to be a lot of pre assembled thermoelectric coolers online for 30-40 USD, for general use of course but I'm guessing some could be attached surprisingly easily.

[hoary cradle]

Ah yes I see, also a lot of them are 12v. Makes it pretty easy

[twin pawn]

Indeed

[short radish]

https://www.thingiverse.com/thing:4306640

Does anyone know if there is any adapter or 3D project of this type for Sony cameras? A5000, a6000...

As far as I know, Sony can only be modified as full spectrum. So I would have to use an IR-UVCUT filter and eventually I would like to use a CLS.

[twin pawn]

Did you already get one of the Sony mirrorless aps-c cams?

Unless your using it for daytime as well I would rather get an imx 533 or at the very least a Canon cam with more filter support.

[short radish]

I'm going to buy a 294. But I need a mirrorless too... Canon can't do it, because its sensor is too far back. It probably wouldn't focus on my telescope

[twin pawn]

Ah yea, that'd be a problem

Focusing that is

[mint island]

Wanted to share this. With 1d mark II and Samyang 85mm 1.4 manual

[fading osprey]

I finally got a pretty nice photo after a while

[next kernel]

modified?

also acquisition please

[fading osprey]

Yup, also acquisition is 4 hours I think

[frozen tinsel]

Hey what lens FL did you use?

I'd like to image it (I have a 200mm) but I cannot seem to find it

Does it show a small line like andromeda does/

[fleet latch]

I didn't use a lens, I used a 130mm Vixen and my DSLR

Sorry, I should have been more specific about my image

[frozen tinsel]

Ohh that's very cool! What's a vixen?

[frozen tinsel]

No problem at all!

Btw can you share your data, i'd like to try it out a bit

[fleet latch]

Sure! Its a telescope company btw

Give me a moment to find the tiff file haha

[frozen tinsel]

hahaha

But did you say it was only 130mm fl?

[fleet latch]

oh no haha the fl is 600mm so its F/4.5

[frozen tinsel]

Ohhh haha okay, cuz I was wondering how you got that with a 130. Do you think its possible with a 200?

My lens is 200mm is it possible or nah?

[fleet latch]

how wide is the lens?

[frozen tinsel]

Also how did you find it?? I cannot find it!

[fleet latch]

diamater*

the galaxy?

[frozen tinsel]

The diameter of the galaxy is M33

Im not super sure haha

[fleet latch]

So the name of the galaxy is M33

Messier 33

[frozen tinsel]

Yea thats what I want to get

Yep

[fleet latch]

yeye

[frozen tinsel]

Is it possible with a 200?

[fleet latch]

Do you know your Focal ratio?

[frozen tinsel]

For the 200?

[fleet latch]

yes

[frozen tinsel]

ITs F 2.8

[fleet latch]

what kind of camera?

[frozen tinsel]

Its a canon EOS 6d Mark II

[fleet latch]

one sec

[frozen tinsel]

KK

[fleet latch]

the red box is your camera and lens FOV on M33

so you can very much capture it, just not as magnified as my image

[frozen tinsel]

Ahh cool. Can you crop it?

[fleet latch]

its (in my opinion) an easy target

[frozen tinsel]

Would that work? I captured andromeda with an 85, cropped it, and it turned out really nice

[fleet latch]

I mean once you have a fully stacked image and crop it during processing

[frozen tinsel]

(I want to reget andromeda with my 200mm lens)

Alr. But how do you find it

I spent so long looking

[fleet latch]

In the sky?

[frozen tinsel]

Yeah well I live in a bortle 7 lol

[fleet latch]

ohhhhh that makes snese

sense**

[frozen tinsel]

yeah so its not visible

I have to find it

[fleet latch]

do you have a mount that can track

[frozen tinsel]

No, not enough money yet

[fleet latch]

Okay

well the good thing is, your FOV s quite large

[frozen tinsel]

Yeah

[fleet latch]

So if you can get an approximation on where its located, you can take a few test images to see if its in view

I had to do this before I got my mount

[frozen tinsel]

What does it look like? Do you recoomend an ISO?

[fleet latch]

also, here is the tiff : )

[frozen tinsel]

Thanks!

What does it look like through a 200 (single frame unprocessed straight outta the camera)

[frozen tinsel]

Do you see like a small core thing like you do with M31?

M33_YE 😂

Love the name

[fleet latch]

ye lmao

And i am unsure, M33 isnt as bright as Andromeda

and the core of M33 is bright but not nearly as much

[frozen tinsel]

Yeah, so how can I know if I got it or not

Should I like get a frame, run it through the Astrobot

see if it sees it?

And just continue from there?

[fleet latch]

That could work!

I havent used the bot much tho haha

I should also say, the data for M33 is only 30 mins (it got cloudy after) but im gonna get a few hours worth tonight

[frozen tinsel]

Cool!

Thanks

@fleet latch Def not the best but heres my go

How do you like it?

[fleet latch]

Thats pretty good! PixInsight?

[frozen tinsel]

Nope, I used siril and Darktable.

(Both free programs)

[fleet latch]

I can't seem to shake the noise :/

Only done in Siril

[frozen tinsel]

Ah yeah

The noise is really bad

more signal tho get more

[next kernel]

no one can show you that. you have to do that on your own

Ah @languid haven you're shooting with a d7000 right?

[languid haven]

Yes I have a d7000 although I recentely upgraded to a d750

100 bucks is a great deal

What is the shutter count?

[hoary cradle]

25473

Stil pretty low I think

[languid haven]

Yes that is pritty good

[hoary cradle]

I thought expected life is like 150000

[languid haven]

and the d7000 had a build in intervalomiter so thats good

[hoary cradle]

I also have a d5300 but I want to try out a astro mod on a other camera

[languid haven]

Are you tracked?

[hoary cradle]

Probably will use it with NINA but that's good to know though

[hoary cradle]

Yes

[languid haven]

The d7000 maxes on 30s exposures and you need a very expensive cable to go over

Like 80 bucks but you can also make a diy cable

[hoary cradle]

But it is sdk supported right?

[hoary cradle]

Ah will look into this, thanks for the heads-up

[hoary cradle]

That's insane haha

[languid haven]

Yes its mad

[hoary cradle]

D750 is full frame right?

[hoary cradle]

I assume you made one yourself?

[languid haven]

no I was kinda just chilling with with 30s becouse when I started guiding I wanted to go over 30s ofc, but I did not buy or make one of those cables becouse I was planning on buying another camera (the d750) and that one can go over 30s

but you can go over 30s with an external intervalomiter on the d7000

[hoary cradle]

Ah yes I see. After some reading I indeed see there is a serial cable (dsusb?) for shooting with over 30 subs. Just haven't found how to make it or where to buy it exactly. And it probably doesn't work with NINA so maybe BYN is a option

So a bit of trouble but maybe worth it. Again €100 is a steal with the Tokina 12-24 included

[languid haven]

yes def

but if you aren't guided its no problem becouse you can just buy an intervalomiter

[hoary cradle]

Yes but I shoot guided. Going for it anyway, fun to hobby around with it and otherwise I'll sell it I guess

I can't imagine there isn't a Chinese company who doesn't sell these cables right

[languid haven]

idk I could't find them lol

they are very specific

[languid haven]

yes you can resell it and make like 80-100 bucks

[hoary cradle]

Haha nah indeed

Intervalometer it is then

[hoary cradle]

I think there is a good trade in there to make some extra bucks, also bought a d3200 with a broken outer glass screen for €35

Bought the glass for €5 haha

[languid haven]

Hahahahaha lol

[vapid goblet]

dsusb should communicate with nina

look at shoestring astronomy for the cable

http://www.store.shoestringastronomy.com/products_ds.htm

[languid haven]

Sadly they are damm expensive

[hoary cradle]

Yeah for the price it's not really worth it for me. Bought the camera for less. But thanks for the link

[foggy shale]

does anyone know of astro imaging programs that can use a dslr? I have yet to find one that will detect my t3i

[candid walrus]

NINA, APT, possibly sharpcap if you use this https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjczd2RvZKDAxVeVUEAHWnkDS8QFnoECDAQAQ&url=https%3A%2F%2Fgithub.com%2Fvtorkalo%2FASCOM.DSLR&usg=AOvVaw22JPTMwy1G6tCcc1x5GCgc&opi=89978449

[foggy shale]

thanks

[foggy shale]

NINA doesn't pick up my camera, its connected but it doesn't show in the tab for selecting a camera

[candid walrus]

It wont show up in there no matter the camera lol there should be a option "ASCOM DSLR drivers" or something along those lines

[foggy shale]

do I have to download that?

[candid walrus]

Yeah the link i sent above

is the ASCOM DSLR driver

[foggy shale]

ah

[candid walrus]

Then NINA can register the ASCOM drivers and control the cam

[foggy shale]

it says I can't run it on my pc even after I say run anyway

[candid walrus]

click "code" then "download ZIP"

[foggy shale]

should I extract it?

nevermind

it worked

[foggy shale]

thank you very much

[candid walrus]

All good! Happy imaging!

[foggy shale]

actually I thought it was working but NINA seems to crash every time I try to run the camera

sorry to bother you again

[candid walrus]

Dont apologies! when you extracted the files did you open the drivers to set it to Canon and what ISO etc? if not you can also do this in NINA by pressing the gears icon near connect

[foggy shale]

oh I see I didn't do that

[foggy shale]

I'm Canadian apologising in my blood lol! I am trying to do it in NINA but no matter what I do ascom returns an error saying camera is not connected but I have it connected and my computer sees it, any ideas?

[candid walrus]

XD what cable are you using? possibility it isnt a data transfer cable so no data can be transmitted or received, if its one that came with the camera its likely not that, what settings did you select in the ASCOM DSLR driver part?

[foggy shale]

not sure where I got the cable from but I have used it before with my computer to get a bigger live view with EOS utility so I think it is a data transfer cable, I tried both canonsdk and backyard eos, I didn't change the port(that might be the issue in which case I have no clue how to find what the actual port is) I set it to save photos to a folder on my computer and my iso is 800 camera log level is error and ascom trace is still ticked on, Max ADU Overide is not checked, use esternal shutter is not checked and enable binning is not checked

[candid walrus]

Ahh ok likely not the cable then, when you opened up the ASCOM thing did it ask you what camera? like Nikon F, Canon D and stuff like that?

[foggy shale]

no I don't think so

[candid walrus]

Hmm, did you open that menu in NINA?

[foggy shale]

yes and I found in ascom

oh wait it did

like it says select the type of camera you have

etc

[candid walrus]

Yeah did you select the right type?

[foggy shale]

talking about this right?

[candid walrus]

Uhh possibly, click Properties, what does it say then?

[foggy shale]

then its the menu

[candid walrus]

K cool this is the menu, at the top is that the correct thing for your camera? and make sure to set your ISO so its default is whatever you set it as, if the connection method (the top option) isnt correct, then it cant communicate to your camera at all

[foggy shale]

do you know what method the t3i uses?

ill try looking it up

[candid walrus]

Quick google says AF/AE so if theres a option of those two or anything close, try those

[foggy shale]

it only gives me these options

[candid walrus]

Could try the BackyardEOS option as BackyardEOS was working for you, so maybe using that method of connection could work here

If not i have no idea honestly

[foggy shale]

ok

it gave me a different error this time

[candid walrus]

What error did it give this time?

[foggy shale]

actually it is still camera not connected but it gave a different window, before it was just saying camera not connected and that was it

[candid walrus]

Yeah thats definitely a odd error, pretty strange, im sorry but i genuinely dont know what to suggest😅 if you click on the "scan for devices" option on NINA does it auto put it on something? ill try looking for some cloudy night threads about it aswell, see if anything comes up

[foggy shale]

ok well thanks for the help so far

I gotta go have supper but I will go and try and find more later

[foggy shale]

it auto puts it on the v3 simulator

[foggy shale]

I think I found one of the issues but now I am getting this, I tried redownloading ascom but that didn't help, not sure what it means though

what is the driverhelper?

[fleet latch]

2 hours of M33 with a Canon 1100D and a 5 inch vixen

[foggy shale]

ok im getting somewhere I kind of disregarded that and did the connect thing again and my cameras shutter just went/ the mirror lifted up or down( my camera made a noise) now I am getting this error any help?

[candid walrus]

Ok so the camera shutter thing is good, thats what you want to happen, no idea what the errors are, but you could always press "continue" and see what happens

[foggy shale]

yeah

[candid walrus]

Considering it gives the continue option, the error isnt drastic (thats my assumption anyway)

[foggy shale]

good idea

ok

[foggy shale]

so

[foggy shale]

nice

[foggy shale]

This is the older ascom dslr driver guy named FearL0rd took over the project and has brought it up to date so I downloaded the new one but know its giving me the comm port is in use error anytime I try to do anything. One question whats a comm port?

[candid walrus]

Sorry was getting tea lol a com port for my understanding is the com port is the thing thats connected to the laptop by a specific "port" based on what youve plugged in and what it is (like how 99% of times if you plug in a mount itll be COM 3) so supposedly the com port that your cam is trying to use is busy, or something else is trying to use the cam/com port

[foggy shale]

could that be eos utility that is open is trying to use the cam ?

so the prot is busy

[candid walrus]

If its open theres a good chance yeah

[foggy shale]

ok

[candid walrus]

I cant have DigicamControl and NINA open at once otherwise my camera throws a strop at me

[foggy shale]

ok yeah the error just went away when I closed eos utility

YES

IT CONNECTED

[candid walrus]

LETS GOOOO

[foggy shale]

so now I have a question that is probably a lot easier how do you set up nina to take multiple pictures ? This is my first time using it so now I gotta learn it

[candid walrus]

Haha definitely easier thats for sure! in the "imaging" option on the left, after your on that menu on the right it should have a place you can set your exposure length, and id just turn on "loop" and "save", otherways would be to use Sequencer but ive never used that either XD

[foggy shale]

Cool, Thank you so much now I just gotta wait for a day when the clouds part!

clear skies!

[candid walrus]

Haha np! goodluck and clearskies!

[north leaf]

untracked orion

[wild jasper]

Untracked Orion

Yes it needs a star reduction

[candid walrus]

My best most recent images using my Nikon D3500 full spectrum

[fallen grail]

astromodded my T3i last night by removing the LPF1 filter, one of the scariest things I've done holy

Completely lost track of the sensor screw positions so I had to guess and rely on luck to get me proper infinity focus and tilt but somehow I managed to get everything in with proper infinity focus and minimal tilt

Autofocus doesn't work anymore because my backfocus isn't proper haha but oh well, it's for astro anyway

[fallen grail]

Fantastic, what scope?

[candid walrus]

Thanks! Skywatcher Quattro 150p for all the nebulae, and Celestron C8 for the galaxy! i know how you feel with that modification, its absolutely terrifying

[fallen grail]

The Quattro 150P almost seems too good to be true! At the price, you get 500+mm and f/3.45! How has it been doing you with your Nikon DSLR? I may pick one up one day.

[candid walrus]

Haha its unbelievable for the price! its been amazing so far! ofc its got its downfalls for being cheap, but if im honest its nothing offputting enough for me, i love it, but for example the spider has got some rotation in it and arent perfectly straight so the star spikes arent perfect (very fixable though) and its got mirror clips that appear on stars (just needs a mirror mask) one thing ill say for me is that with the DSLR the coma corrector actually sticks out into the tube a little bit, so thats slightly annoying but its no different to having the mirror clips tbh, its only a little sticking out, and last but not least it does get internal reflections quite easily, flocking would be a great consideration for it! but they are all fairly easy fixes, and for a 6" F4 newt with a CC/Reducer to F3.45 with very minimal coma at APS-C, i couldnt recommend it more if your looking at cheap but good performing newts!

[twin pawn]

Travelling that distance for some people is sometimes not an option at all due to costs mostly. My parents visit Florida in the summer only once a year, and that's the most they can in good conscience afford.

[vapid goblet]

My parents cant afford to travel at all

Furthest i go for a vacation is Kentucky, only 1 state away

[inland cypress]

is this roki135?

Tried doing HDR orion. Didn’t really go well but it’s still a ok image ig

Only 2 hours of data

"only"

i've never gotten 2 hours on any object lmao😭

[grizzled cedar]

Why not? It’s easy if you put the work into it

[next kernel]

i live in a bortle 8 and have to travel with my dad to a bortle 5. That in itself is 100km round trip

and my dad works so we can't afford to stay out very late

[grizzled cedar]

You should try narrowband

People get really good images even in bortle 9

[next kernel]

brother i am NOT trynna buy a whole setup lmao

my setup should speak for itself

how broke i am

[grizzled cedar]

You don’t need a whole setup for narrowband

[candid walrus]

Whats your setup rn?

[grizzled cedar]

Just get a duo narrowband filter, there not much

Well

Idk your budget

[next kernel]

camera and lens, tracker

[grizzled cedar]

That’s a good setup

[next kernel]

yup for sure

i'm just saying it's a big jump to narrowband

[candid walrus]

Yeah 2h from B8 would be good, and if you got a Dual narrowband filter thatd make it even better

Lenhance is great

[next kernel]

i'll look into it

[grizzled cedar]

Duo band are not like the mono SHO pictures

[candid walrus]

Plus whats the point of travelling 100km to image a nebula that you couldve from home with a dual NB filter

[next kernel]

i know i assumed you were talking about that tho when you first said it

[grizzled cedar]

No no, narrowband like that is to much for even me lol

[next kernel]

i'd still probably go to b5 even with the l enhance

[next kernel]

yea that requires a whole setup. duoband is different

[candid walrus]

nah you should use it at home and shoot galaxies/broadband targets under your limited time at B5

[next kernel]

ur right never thought about that

[grizzled cedar]

Yea, just look for the l-enhance at a good price it shouldn’t be that much

It’s definitely better than a 100km drive

[candid walrus]

looking at £116 for 1.25" £149 for 2" and £175 for EOS clip in from FLO

Used you may be able to get it for cheaper

[next kernel]

yup

[hot epoch]

can confirm

I live in a b8-9 zone and it works well for me

[grizzled cedar]

I was just messing around with old data because my mount is broken. I cropped into the core of orion and stretched a bit

[mint island]

Breath taking

[hoary cradle]

This on a DSLR? Also with lenhance?

Got this on a d5300 with 1/1.5 hours now

Thinking about a dual band but don't know if I can get my tracking good enough for longer exposures

[grizzled cedar]

Yea with a dlsr. No filter, this was a while ago

[grizzled cedar]

What mount do you have?

[hoary cradle]

Ah I see, cool diffraction spikes btw

[hoary cradle]

SW eq5 pro goto

So with a lot of work it could track good enough I guess. But I'll have to tear the whole mount apart first

[grizzled cedar]

You could definitely do duo band, just get guiding and you should be fine with it

Duo band doesn’t take as much as narrow band. I think of it as a light pollution filter but thinner

[hoary cradle]

I have tracking but the longest exposure I was able to get is 180 seconds. Get to balance the equipment and polar alignment good but still it's having a hard time

[grizzled cedar]

180 secs is more than enough duo band does not take a lot

[hoary cradle]

Ah great, thanks for the info

Any tips on a particular filter?

[grizzled cedar]

L enhance or l ultimate, I don’t really do duo band so fact check one of those (note that the l enhance is broader than the ultimate but it cost less

I heard people getting good results with the sv220 duo band filter to

[candid walrus]

What scope and camera would you be using?

[candid walrus]

Dual band filters are narrowband filters, just with 2 wavelengths instead of one lol

[vapid goblet]

light pollution filters are bad

duoband are not

[hoary cradle]

Im using a 130pds and a Nikon d5300 right now. Also have a sv305 pro for guiding and some planetary mainly

[hoary cradle]

I'll look into this one. I'm into budgetty things haha

[candid walrus]

Assuming the D5300 isnt modified id go with a Lenhance rather than the SV220 or L ultimate

[hoary cradle]

No it's not modded, lenhance is less narrow?

[candid walrus]

Yeah the L enhance is 10nm while the SV220 is 5nm and Ultimate 3nm, having that wideness is useful for a non modded DSLR as they already lack sensitivity due to the built in filters

[hoary cradle]

Ah I see! Thanks a lot

[candid walrus]

Np!

[grizzled cedar]

I didn’t suggest a light pollution filter

M33 Reprocess - Stock 50D

[mint island]

M81 group. 25 minutes of data.
Untracked, Canon 600d, Samyang 85mm f1.4, stacked and processed with siril

85mm is the problem here, the object looks too small. By gathering more photos, will i get a far better picture, since not a lot of details can be captured by just a few pixels?

[wild jasper]

yes

[grizzled cedar]

That is how that works

[mint island]

Guys, is m81 brighter than m33?

[next kernel]

m33 is brighter

much brighter

[mint island]

I guess m81 "appeared brighter" because it is closer to Polaris, which allowed me to use a slower shutter speed, but whatever, here is 28 min of untracked m33

I will go somewhere really dark this summer over night, because my backyard is quite lit up, the horizon is like really bright and stars are hard to see because of light pollution

Oh damn, thanks

[frozen tinsel]

Yeah, I am using an 85mm F1.4 doing the andromeda, and even though its so small but all that data lets me crop it and still get insane details

[left vigil]

I am thinking of modifying my canon eos 2000d (removing the filter)
And using a dual narrowband from a city with a 130pds
Is this a good idea?

[candid walrus]

Great idea! i modded my D3500 awhile ago, and it really helps with nebulae, adding a dualband made it even better too

[left vigil]

Even from a light polluted city?

[candid walrus]

Absolutely

[fleet latch]

My first shot at the horsehead

I didn't take enough darks and therefore have a noise problem

I think there was also dust on my sensor?

[fading osprey]

Sure looks like it

Just take some flats

Also a lot of that noise is walking noise so it can’t be removed without longer integration or less harsh processing

But most of that noise seems to be color noise so you could do color noise reduction to help get the background a bit more uniform

[fleet latch]

Will try this tomorrow

[fleet latch]

I did take flats but I think not enough,

[fading osprey]

Then you probably want to invest in a sensor cleaning kit

[strange gazelle]

hi i have a full specturm dslr and i was wondering what filter would compliment the pictures

[thin salmon]

What brand?

And what lens/scope?

[strange gazelle]

im using a ts photoline 80ed with a canon eos2000d

[thin salmon]

If you're using a dedicated scope, you can probably use normal threaded filters. The best one is probably the l-ultimate, but an apl-t or l-extreme are good options as well

[fresh frigate]

Would it be better to get a filter for the front of my camera lens, or get a filter drawer?

This is not for narrowband, just for a diffusion filter for soft colorful stars

[strange gazelle]

im thinking about getting a deditcated astro cam in the future but and i was wanted to know which filter would be good for the dslr and one i can possibly use with the astro cam

[strange gazelle]

[left vigil]

How do i connect a 2 inch filter to my canon dslr
My telescope is a 130pds

[fresh frigate]

If you're going to be using different filters throughout the night, probably use a filter wheel

[left vigil]

Just one filter for the moment

[twin pawn]

Can't get proper spacing with a fw and a dslr

[twin pawn]

Do you have a coma corrector for the newt?

If so it should have 2" filter threads on the bottom... If you don't have a CC then any 2" nose piece that slides into the focuser should have 2" filter threads as well.

[left vigil]

Can i 3d print it?@twin pawn

[twin pawn]

A 2" nose piece could be 3d printed for casual imaging use but can cause issues simply due to the fact that it's less rigid than metal and the needed thread pitch is likely too fine for fdm printing.

Resin printing is likely too brittle but not quite sure I don't have too much experience with resin.

[vapid goblet]

i wouldnt trust plastic to hold hundreds of dollars worth of equipment

[fading osprey]

I have bad experience with that

I’m never using printed parts again for screws or a base to anything

Luckily i noticed it and caught the cam and ball head

How do you guys take proper darks with a dslr since the temperature changes?

[fading osprey]

You don’t

I just take 15 at the beginning of my shoot and 15 at the end

then just hope it kinda averages out

[left vigil]

Does it work?@fading osprey

[twin pawn]

As long as you have darks that are no less than around 3° at the beginning of the sequence and no more than around 3° at the end of the sequence you'll see an improvement, especially if your dealing with walking noise or amp glow.

+/- 3° of your average light frame temp

Just a good rule of thumb.

If you have a several dark frames throughout the session that actually match some of the light frame temps than your set.

[left vigil]

Do the fan modifications work?

[fading osprey]

Yeah i guess, i live in a very hot climate (70-75 degree nights) so it’s hard to tell

[left vigil]

I am thinking of putting a fan and a peltier cooler on my dslr

[next cobalt]

E

[fading osprey]

that would be pretty simple, the back LCD unscrews normally and you could measure it out and print an adapter

[frail briar]

Sorry for replying to an old post but it seems no one knows this: Canon DSLRs (at least the older ones) have a temp sensor inside - NINA and APT can read it and you might be able to read it in windows file explorer. I just took a bunch of darks outside over an entire rainy night (under roof of a balcony and noted down the tempature for each dark - you can most likely get the same temp. another tactic is stick it in the fridge or freezer. Another thing is that darks colder than the lights will correct less but will still work while darks hotter will start to remove data

[left vigil]

I might try the fridge thing
It sounds cool

[frail briar]

be cautions of condensation though, can get annoying

[north leaf]

should I go for the nikon d7500 or z50 for astrophotography and general photography? for the z50 I'll need an adapter and the dumb ones are bad, with both i plan to use the roki 135

[brazen crystal]

perfect, im untracked as well and have been wondering for a while if this target is possible

how long was each individual exposure?

[twin pawn]

D7500 seems solid, has a IMX 321 from what I've gathered online.

Z50 is likely a newer sensor but yea a good adapter can be quite a bit.

Although you should be able to find a non AF Nikon Z to F adapter for way under 100.

[brazen crystal]

whatever u do dont go for the d3400, ik that wasn't one of ur choices but it doesn't have a remote shutter release port

make sure whatever camera you buy does

[north leaf]

adapters are chaotic, cheap ones can only take full manual lenses because you can't even co trol aperture of standard lenses and they get many focus and tilt problems

native mounting is the best

[mint island]

Hi, sorry for late reply, one sub is 2.5 seconds

[brazen crystal]

[north leaf]

I just purchased the nikon z50, it should work with ascom dslr driver right?

Stars might have trailed a bit because of winds

[brazen crystal]

what tracker do u use? i want one but i dont wanna go broke in the process

[grizzled cedar]

I use the star adventure 2i, that’s probably the cheapest good tracker there is

[slate sapphire]

What scope

[grizzled cedar]

Orion spaceprobe 130st

[slate sapphire]

Isn’t that like a small Newtonian

Oh nice

[grizzled cedar]

Yea

[slate sapphire]

Nice was thinking about buying one!

But not anymore I’ll stick to only a camera no scope

[grizzled cedar]

I wouldn’t recommend it tho if you wanna do photography with it, because it’s made for visual

[slate sapphire]

Yea I know

[inland cypress]

mod canon 6d

[wild jasper]

i feel the DSE is a bit too strong

apart from that, image looks amazin

[wild jasper]

like once you notice it, you cant get your eyes off it

[karmic shoal]

What are the best targets/category of targets for a stock dslr?

[wild jasper]

anything oiii
galaxies
dust

[grizzled cedar]

All i have is clouds so all I have is old data to process

I didn’t notice that I almost got some of the background dust in the image till I processed it better now.

[cerulean sky]

This is just the stacked lights, edited, but no callibration, also in b9

Stacking it with dbf right now

[cerulean sky]

Much better than my last ones

579x1/1.3s

10000iso

b9

f6.3

I imagine how the image wouldve been if the lights were taken at b5 or lower

[twin pawn]

Why the mustard yellow?

[ivory notch]

M101 Nikon D5500

[cerulean sky]

No idea

Couldnt correct it

[cerulean sky]

But calibration frames removed it so maybe it was the light pollution

[fading osprey]

Just use the hue slider in lightroom or whatever you use, then turn down vibrance and the color u are changing the hue of’s saturation down to blend the color nicer

Also those colors probably aren’t accurate bc my phone screen is tinted rn

[cerulean sky]

Oh nice

I tried playing with hue but i clearly didnt try it enough

[hoary cradle]

Hi

People are working with Nina here?

I'm always using a trusty Nikon d5300. Always works and never had any problems. Yesterday I wasn't able to connect to Nina with the error of 'unable to adjust shutter times'. I was in manual and everything setting was ok. I was able to connect to digital cam control as well..

[grizzled cedar]

Maybe is the cord your using?

[hoary cradle]

Wel I doubt it because digi cam control is working fine with live view etc

[strange gazelle]

Canon EF 75-300mm f4.0-5.6 III Anybody know anything about that lens? Is it any good?

[strange gazelle]

Using a USB dongle?

I had issues with mine and then I connected my 2000D directly with mu computer and no issues since

[wild jasper]

Its pretty awful

[shadow shoal]

i own it, it varies from bad to terrible, i think if you point it somewhere high the internal elements get moved slightly and the stars become terrible

[karmic shoal]

are you using the right Iso for your camera?

[shadow shoal]

these are both stacked photos

the difference is how terrible the stars are

[karmic shoal]

Ik, but changing the iso could improve the noise to signal ratio

[wild jasper]

the issue is the lack of signal thats it

changing the iso only reduces the read noise slightly.

[karmic shoal]

theres also some star trailing in the first image

[shadow shoal]

the intended focus of the images was "oh in the 1st image the stars are normal, but in the 2nd they are triangles"

[karmic shoal]

The second image could be out of focus

[shadow shoal]

nope

[karmic shoal]

could it be caused by a glare?

[candid walrus]

You using a newt?

If so your collimation is far out, or possibly pinched optics

[shadow shoal]

no just the cannon 75-300mm

[candid walrus]

Still a good chance for pinched optics then

[shadow shoal]

#1034767907495874572 message

[candid walrus]

I’d imagine if that was the case it’d appear regardless of direction, but also knowing those lenses, they probably would do that XD

[shadow shoal]

either that or its a temp thing

[candid walrus]

Yeah which’d be pinched optics, nothing a dew heater wouldn’t fix

[shadow shoal]

i think what im gonna do is just not use it and use the tpo ultrawide 180mm, which doesnt do that

and gets more light input

i may be stupid

[pliant viper]

have you tried stopping down your lens

[north leaf]

bad, get a prime

[karmic shoal]

Practice on Arcturus, a red giant star. Before processing the beehive cluster.

[strange gazelle]

Oh that does look bad, I was considering a cheapish lens I could buy for landscape/ normal (animals etc) photography

[strange gazelle]

I usually use a photoline 80ed for astrophotography which is my way to go. I have a 150/750 ts optics newt but I hardly use it although I love the spikes of the stars it produces…..

[karmic shoal]

Beehive cluster on the 24th.
Unmodified Dslr, Untracked
~3 minutes total exposure, Iso 800, Calibrated
3.2 sec single exposure time
Bortle 4-5

any tips for improving this next time?
(Besides get more data, lol)

[shadow shoal]

what lens?

[karmic shoal]

Stock

[shadow shoal]

do you know what mm it is?

[karmic shoal]

no

[shadow shoal]

what camera is it?

[karmic shoal]

Rebel T100 Canon

18-55mm lens

[shadow shoal]

yeah that isnt enough focal length (i think)

[karmic shoal]

I'm gonna get it hooked up to an 4.5" newt soon. Just waiting for clear skies to test it

[amber echo]

the cannon EF to nikon F introduced some aberrations. It's my second astro pic

[slate sapphire]

Noice

[slate sapphire]

Noice

[final mortar]

Canon 550d
Tamron 70-300 lens

[slate sapphire]

Very nice

[final mortar]

Thank you! but I really don’t like the “oval” stars in the photo

[slate sapphire]

No it’s great still

I have heard about a solution to such stars

I don’t remember it tho

[north leaf]

blurx

[slate sapphire]

Hello

[final mortar]

Hi

[strange gazelle]

does anybody know what is causing this problem on the top?

okay looks like it was a bad flat frame

[mint island]

Didn't know there's a 4th galaxy right there

Epic, I also have it in my photo

[strange gazelle]

seem like my flat, bias and darkflat were bad

[mint island]

That also happens in the photos, the picture gets lighter from top to bottom, idk why my flats are bad

[cerulean sky]

Did you run background extraction?

It would atleast somewhat reduce it

[timid flint]

any dslr recommendations

[strange gazelle]

Gets a lot more worse

[cerulean sky]

Damn

[strange gazelle]

Might just be dust etc on the optics bc left the scope out for 3 days, capped it though during the day

.......

Pollen 😅

[strange gazelle]

Eos 2000d/ rebel t7 I use that, cheap and produces good pics

[fading osprey]

Buy one of my astromodded 450ds (They honestly work well as long as you don’t have 70f nights)

Just make sure the pixel size fits ur scope well if u do consider buying one

[bright swallow]

My first image with my Canon 450D, also just wanted to ask if there is any way to stack RAW images from my camera?

[fading osprey]

I’m pretty sure you can drop cr2s into deep sky stacker and go from there, or use sequator which is what i used to do when i shot without Asiair, but it kinda sucks

[bright swallow]

Alright sounds good I’ll have to check DSS tomorrow thank you

[strange gazelle]

Why does the camera have a black border/ vingetting on top?

Looks like it's the shutter speed 1/4000 might be a bit too short. 1/2500 works out well

[mint island]

C/2021 S3 comet at 85mm (obviously cropped in)

[vapid goblet]

They're the same picture

[cerulean sky]

Got a diffraction spike filter

Also found a 40yr old 300mm lens, which goes to f4.5

Much better than the f6.3 i had

[short radish]

@regal edge has one

[mint island]

Look in the middle, a faint tail appears and disappears

[grizzled cedar]

4 hours on Sadr butterfly nebula
Canon EOS 4000D modded

[cerulean sky]

Took 11mins of horsehead at 8000iso today, will take more 11 mins in the next few days

Until i get 1 hour

[grizzled cedar]

Why at 8000iso?!?
Way to much, your just gonna show a bunch of noise

[cerulean sky]

Bortle 9

I can deal with the noise in post

Plus if i went with lower iso, i would need more exposures, and by the time i was done today orion was almost gone

Some buildings block it

[cerulean sky]

Even with that i couldnt get anything damn

If anyone is able to get anything out of it

Ill try horsehead again when im not in bortle 9

[sour ore]

all stock setup, including the lens. stock t3i and stock 75-300mm

and yall say this lens is terrible

[round salmon]

stock d3300 and a 70-200mm lens I accidentally dropped

[vapid goblet]

this depends on the camera

higher iso gives less noise, but at the cost of dynamic range

[north leaf]

hoe much exposure time

thats very good

[round salmon]

just over 4 hours

[north leaf]

thats very nice

[round salmon]

yeah, I’m pretty happy with how it turned out, although I should probably start looking for a new lens or getting it repaired since the decentering on this is almost unbearable now

[north leaf]

haha

true

but the image is amazing

u should buy a new lens if you ask me

a prime one with higher aperture

getting more data in less time would be easy then

also repaired lenses have problems in the future too, factory onrs are sweet

[round salmon]

Yeah, I’m looking at the Nikon 300mm f4 one right now, I’ve seen people say it does really well

[north leaf]

no

dont go for

nikkor lenses

they are very costly

look into third party ones

[round salmon]

Vintage lenses are pretty affordable

[north leaf]

like tamron and rokinon

true

and work pretty well

[round salmon]

And they’re built like tanks

[north leaf]

i use the samyang 135

[round salmon]

I would have got one but I just prefer longer focal lengths

[north leaf]

this was a 32 min exposure at bortle 4

[round salmon]

Good copies for it are just stunning with how well they perform

[north leaf]

this was a 10 sec exposure on bodes

[north leaf]

yup

at f2

the stars look very bad

but when u shift to f2.8

its amazing

[round salmon]

Yeah, it saves an insane amount of time dropping down to even f2.8

[regal edge]

Have you ever sh0oted using it?

[cerulean sky]

Tested it yesterday on horsehead, light pollution ruined it but the stars came out nice

Got this shot of sirius with it tho

Note that this is unstacked and edited

[regal edge]

send a photo of the lens, and a raw file please

[cerulean sky]

ill do it in a few hours

[grizzled cedar]

I’ll try it out when I get the time

[sour ore]

Lower iso isn't always better

[grizzled cedar]

I know that but 8000?

[sour ore]

Yeah I agree it's a bit much

[bright swallow]

Earth Shine

Can anyone open it?

[shadow shoal]

not through discord

[bright swallow]

Oh dang okay and one thing I don’t like about my image is the crescent reflection you can see by the moon

[shadow shoal]

oh i didnt even notice until you brought it up lol

[dense yew]

What lens and settings did you use for that?

[bright swallow]

https://tenor.com/view/fade-away-oooooooooooo-aga-emoji-crumble-gif-20008708

I should’ve stayed silent

[twin pawn]

@btc.777lol as @fading osprey said the 450d is solid for the money, especially when modified.

All with a modified 450d and small frac

Duoband filter under bortle 6 skies

All around 4hrs integration

[round salmon]

Core is blown out, but I’ll get to fixing that a bit later. Stock d3300 w/ Nikon 300mm f4 IF ED ~ 3.5 hours integration

[fleet latch]

6 hours on M51 with Canon 1100D

[wild jasper]

stock dslr untracked

[north leaf]

Will it be safe to connect my camera with the samywang 135 to this?

it's a head from theyripod i use

it fits nicely on the dovetail plate

I'm just concerned bout the weight of samyang 135

[final mortar]

Stock canon 550d
Tamron 70-300

[twin pawn]

Should be fine as long as it's secure

Kinda like a makeshift riser block lol

[north leaf]

it wasn't safe

started bending when I put the roki on lmao

[twin pawn]

Ahh yea nvm

[north leaf]

I'll stick with camera mounted on dovetail abd secured with velcrow

[grizzled cedar]

Does anyone have or know anyone that has the Canon EOS 4000D dslr? If so what mini usb cord can be used to connect my camera to my windows computer (preferably on Amazon)? Mines recently broke

[amber echo]

i found this on ebay at a great price https://www.ebay.com/itm/276448638151?itmmeta=01HZ5AGCSMMCKQ1BGNW6QMJAA8&hash=item405d9f74c7:g:0mMAAOSwpJ9lmInV&itmprp=enc%3AAQAJAAAAwEclMhxY8XkJBk0XWDb%2BZ3Dd4Pv82hLp3XvGwy3UMnNMdHIxjN06y5hF1NamhnqXsi4gSc8COTPwHDmu%2BKZBG%2FTPqQBH7sycenpNQnfrW31QF4Vo3bWFg%2FaRA7UYz9Hkg54yd8rBkT0GgkbQr61b6M0f06yrzpVQOCM6L%2FyTMQwYgIOVzdWLtDKcWQfdkz5cflPLMhfhSpNt%2BuahXE2K4Bk6p6MOtrHcIrwZl9C1l3qWyzmC8lfIvbp5j%2F2oJ%2BQI%2Bg%3D%3D|tkp%3ABk9SR_DMwar5Yw

[lament agate]

Nikon D3300 and 300mm f/5.6 zoom lens

[hoary cradle]

Would like some feedback on this. First time doing some milky way shooting. Editing was a pain in the *** and the lens had some flare from the neighbors camping next to us. Had the 'luck a car drove by in the middle of the night and exposed the trees for a moment. Also lens fogged up after 30 shots or so and of course I don't have a heater

[north leaf]

was this tracked?

[final mortar]

Yes, it tracked with a “homemade” tracker

[north leaf]

oo ok

barndoor.

?

[final mortar]

rather on a spring

[north leaf]

what is that

i have a full german equatorial goto mount

but id like some tskr and go mount too

for mysamyang

135

[final mortar]

just trust me, it works and works very well

I know why you are surprised, this tracker is made only in Russia and only by one person

[hoary cradle]

Modded?

Stock d5300. About 7 hours

[hoary cradle]

It's cool, does he sell globally?

[final mortar]

I don't know, but it's unlikely

[hoary cradle]

I see, curious about the spring system you mentioned though

[final mortar]

It works like an alarm clock, you wind the spring and it transfers energy to the rotation mechanism and with the help of “something” it synchronizes the rotation with the speed of the rotation of the earth

[sour ore]

that denoise tool is funky

[open musk]

what dslr should I get (im using 150/750 telescope with it)

so i just need the body

[grizzled cedar]

8 hour Iris nebula with canon EOS 4000d

[high gazelle]

I have a canon 90D with a EF 75-300mm f/4-5.6 III USM lens. this is my first attempt at shooting the moon. I think in came out ok let me know what you think?
the first one in unedited jpeg strait from the Camera. the other is the raw edited in Digital Photo Professional 4.
