Single Sub Challenge

[lapis glen]

What’s confusing?

[half maple]

A simple screenshot from Nina tn - 300s Ha sub of IC 1805

[light cape]

i cant do 5minute broadband subs

[graceful kraken]

might be at like f8

[true cargo]

🔥🔥🔥

[lapis glen]

Weird

Maybe cuz u shoot open at f2.8? Idk

[hardy field]

300sec sub of the cone nebula and the christmas tree cluster

[muted bough]

180s exposure on cone from almost exactly 1yr ago i think with the 585

[lapis glen]

Woah

[lapis glen]

Thanks for the object idea

[mortal axle]

WTF HOWW?!?! WHAT BORTLE?? DAMN

[rose moth]

I'm curious about what may have caused this intersection:

[plucky heath]

Satellite overlapping

[plucky heath]

Probably 3 or 2

[rose moth]

Interesting how the trail splits and doesn't fully intersect.

[lapis glen]

Holy

[plucky heath]

That is wierd

[noble mountain]

Really big muon crossing over the satellite path maybe? Or possibly a fainter satellite crossing the path and fading out

Don’t think it’ll be a muon as that is large

[crude rapids]

Mewon

[muted bough]

looks like a satellite trail

[narrow plinth]

Dude it’s ass wdym

[half maple]

Definitely not ass compared to some MW images I've seen

On par with most single subs from phones

[graceful kraken]

30s dslr shot

*i was by a house at the time

[half maple]

Dam those skies actually look fairly dark

[graceful kraken]

i lied it wasnt a phone

actual phone shot

[graceful kraken]

they were

sadly they are a continental united states south so Im probably not coming back lol

[lapis glen]

No

[hardy field]

300 sec on flaming star nebula

[lapis glen]

woah

[stark musk]

60s sub. Obviously processed and heavily denoised but still pretty good performance from the 650D

Same sub. Unprocessed

[half star]

what bortle and scope? I have a 600d and can only get that kind of result from a 3 minute exposure at f2.8

[stark musk]

Bortle 5, But my dslr is full spectrum modified And it was with l-enhance filter. Scope is Evoguide 50ed with starizona flattener

[half star]

ah ok i would assume the filter would be the main difference here

mine is also modified

[cunning wraith]

does a mosaic of single subs count?

[lapis glen]

yes

[muted bough]

theres practically no noise 💀

[narrow plinth]

bro thats perfect

[plucky heath]

What even is that

[muted bough]

Carina

[lapis glen]

single 50 sec sub from bortle 5

[stark musk]

already better than your stack from bortle 9

[lapis glen]

Muehehehehe

[opaque finch]

5min sub

I HATE AMP GLOW ARRRRGHHH

at least i can pretend its from alnitak hehehe

[heady forge]

lol thats actually a good excuse

[lapis glen]

I thought it was alnitak at first even lmao

[opaque finch]

its real clean in the stack though which is good

[narrow plinth]

asdfghjkl;'

[muted bough]

Honse

[wise shore]

single 1s sub with my new scope and camera

[sleek bear]

533 mono?

[wise shore]

close! its a 571 from touptek. been really happy with it so far. here is a 300s sub. I blew out the core at only 200 gain

[sleek bear]

oops

you cropped it to a near exact 533 aspect ratio

but the 571 is fire, cant wait till the day i order one myself

that is my goal for the end of the year

[wise shore]

300s Ha channel 👀

[wise shore]

got mine off aliexpress for the price of a zwo 533 so far is been a great camera

[noble mountain]

You did get the TEC cooled not fan cooled right?

[half maple]

Ngl you prolly should have gotten one from Nokk, but hey if it's the normal tec cooled one then it should be solid.

[heady forge]

what bortle and scope?

that looks amazing for a 1s sub

[wise shore]

they don't make a non tec cooled one of the 571 actually. its the regular tec version

its slightly weird as the temp probe seems to be miscalculating temp by around 10-15c higher than it actually is but that is not to big of a problem

[wise shore]

did talk to nokk but theve raised their prices and I was only really willing to spend 1k and 2k lol

so far it seems to be completly original

[wise shore]

B4-5 Quattro 10" @ F3 with Nexus

its a crazy setup

[noble mountain]

Touptek do

[wise shore]

hmm well its not on their website, maybe its discontinued? or are you talking about touptek photonics regular stuff and not touptek astro?

[opaque finch]

[heady forge]

interesting reflections

sirius and fireworks

you can call this a single sub right? this is just a screenshot of a single frame from a video

its noisy cause i had my exposure time set to 1 ms

[opaque finch]

yup

[wise shore]

dont wanna be that "um ackutahly" guy but thats a cooled one, look at description

toupteks atr3/atr are cooled only iirc

[noble mountain]

“Fan cooled” not TEC cooled, very major difference

[wise shore]

I have to be the um ascutally guy I'm sorry

I think the fan cooled part is a mistranslation anyways

G3C is fancooled and they look like this

[noble mountain]

My apologies, always thought fan cooled meant fan cooled too

[wise shore]

all good all good, sorry too but my soul woulda died if I did not become what I swore to destory. the um acuatalalasidhlly guy

[noble mountain]

No worries, I don’t mind those people aslong as they are correct lol

[opaque finch]

google translate was not locked in

[hardy field]

300 sec of m78, poor seeing as per usual of this time of year

[opaque finch]

thats poor seeing?

[hardy field]

An app that I use claims that there was poor seeing last night (not sure how accurate it is though)

[noble mountain]

Meteoblue? they are very inaccurate, if you have pix you can test your seeing using subs with your FWHM

[plucky heath]

What about clear sky chart

[rose moth]

The seeing forecasts online are not necessarily the best. I've been outside in conditions rated poor and it was better than that, sometimes substantially so. The best way is to get outside and look.

Honestly if you look at the sky and see high alt stars (say above 45°) twinkling/shimmering, you're probably not going to have a good time of it.

I think @fair lion sent this link, and honestly I think it should be pinned in the AP chat.

https://www.damianpeach.com/pickering.htm

[plucky heath]

Stars in my area never shimmer sometimes they do but just barely

Like you have to star for a solid minute or so to see something

[shut ether]

Single 300s lum sub from Bortle 1

[half maple]

That's actually nuts wtf

[sleek bear]

Man, that's tasty

[shut ether]

there's a reason why people do remote observatories

[rose moth]

Awful long walk from me to the nearest clear sky, let alone B1

[opaque finch]

WHAT

the core doesnt even look that bad

how much of it is clipped?

[plucky heath]

Yeah but then i won't be able to spend time with the homies and do astro

[lapis glen]

Wtf

This isn’t normal

[shut ether]

linear

[opaque finch]

thats insane

ur HDR stack doesnt even need much int

like 2 mins would do just fine

[shut ether]

well I have about 24h total integration now, I will see what I can do with that (I need more RGB tho and want to add Ha as well)

[opaque finch]

ngl if it were me i would just do LRGB

i feel like orion has enough reds in broadband

i really love a good LRGB orion

https://discord.com/channels/794642864218439681/1184553998850740367

[half maple]

I think Ha addition can be great, especially since it's kind of refreshing from the usual pure broadband.

I went crazy with my addition , something a little more subtle would be even nicer.

[opaque finch]

agreed, for yours i think you could tone it down, although it was really cool to see the Ha you got

[rose moth]

I'm going to thumbs up this, all I could ever get out of my cell phone for Jupiter was a bright white spot. At least you got a hint of the bands.

[zinc helm]

Thanks

[lapis glen]

Wait this isn’t real right 💀

[oblique briar]

It is 🙂

[lapis glen]

holy

How tho, 120 sec

Doesn’t make sense

I have a hard time believing it but damn

[mint depot]

600 not 120

[lapis glen]

Oh I was looking at another sequence mb

[muted bough]

just fit autostretch or whatever it is, 10min narrowband sub on carina

[lapis glen]

https://tenor.com/view/holy-moly-gif-2379897567703251318

[charred berry]

Bortle?

[muted bough]

2 after moon set

[lethal laurel]

damn crazy shot dude

[lapis glen]

Thanks

[graceful kraken]

if you can spot the comet you win

[opaque finch]

not super hard tbh, is that G3 or A3?

[graceful kraken]

a3, just to make sure, where is it

[opaque finch]

slightly left, tail pointing left up, almost touching treeline

[graceful kraken]

congrats

[opaque finch]

must be from a while back

before or after perihelion? i cant tell

[graceful kraken]

yeah, october 12th

[opaque finch]

ah ok, so after

[narrow plinth]

the sub is alright for the image it produced

[half maple]

Single 300" Ha sub

(Screenshot unfortunately)

[main star]

Is that recent? The moon seem to be really close to that area at the moment

[half maple]

Like 2 hours ago

But yea it's Ha so, less affected than say, OIII.

[opaque finch]

spaghetti looks kinda like velasnr

[cobalt spear]

NOT MINE!!
180s sub taken in La Palma

Just thought I should share this because it's amazing how low light pollution affects your images

[sleek bear]

That is incredible

[half maple]

yep, I like how the south and north have twins for each target lol.

[half star]

how is ur detail kinda mid for the single sub but like 10x better for the full one

does it really make that big of a difference?

[mint depot]

osc subs arent like mono subs, so yes

[half star]

how long is each sub and the total integration?

[half maple]

That raw sub wasn't full res

[hardy field]

300 sec on the elephant trunk nebula

[wise shore]

my new scope on jellyfish👀
180s with no cooling (it wasnt cooling for some reason...)

[woeful pewter]

Single 300s Ha with my RASA 11. Uncalibrated and autostretched. Taken at -15C with my beloved 6nm Astronomik MaxFR Ha filter

oh and bortle 5

[lapis glen]

Holy moly

For a sec I thought it said unstretched lol

[sleek bear]

a single raw 300s sub in Ha

[muted bough]

60 second sub from the new LMDSS remote 10" f4 noot

(Halpha)

[woeful pewter]

that's absolutely insane

only 60s at f4! that must be some incredibly dark skies

[muted bough]

its normally low b2 but the moon really messing with it

[woeful pewter]

damn

Carina nebula is just bright as shit i guess

[opaque finch]

is that marks image?

[opaque finch]

im not sure about "low" b2, the horizon lights from bendigo are getting pretty bright

[muted bough]

ah yeah havent been in a while

[boreal palm]

6sec

[hardy field]

Another 300 sec of the elephant trunk, but with no moon this time

[narrow plinth]

bortle 36 be like

[muted bough]

Single 12s sub on C/2024G3

[heady forge]

god damn

[lethal laurel]

southern hemisphere getting a NEOWISE

[lapis glen]

Stop flexing

Bro this is insane

[hardy field]

300 sec sub of the elephant trunk nebula (again lol), but this time just a uv/ir cut filter.

[neon valley]

I dont see anything💀

[astral latch]

in the middle there is a little red ish thing

[neon valley]

Oh yeah i forgot to mention that im blind

[hardy field]

yeah its extremely hard, this is just a screenshot from the asiair so compression is killing it lmao. Its a bit easier when looking at the raw file though

[neon valley]

Yeah i know

[lofty snow]

just wanted to check off some messier objects so just did one sub each

[hardy field]

300s on m81 and m82

[junior bridge]

55s Sub on m46.
Xiaomi 12 + 114/900mm (f8) newt. B4 with full moon
Ignore the vignette and the broken spike in the left corner. The phone adapter had broken, so I couldn't align the phone properly with the eyepiece that day

[cobalt spear]

Crazy what you are doing with a phone

[half star]

why do 6 spikes change shape like this so easily i have the same issue

[junior bridge]

It's hard to explain, but it's because the misaligned phone on the eyepiece basically obstructs or fails to capture part of the mirror at the edge. So, it's basically like half of the mirror at the edge stopped existing, and with that half, one of the secondary's vanes. This ends up altering the spike's shape.

This doesn't happen as easily with a common 4-spike pattern because the secondary also has 4 vanes. So, when one vane is obstructed, there are still 3 others aligned. Even if one vane is missing, the spike remains the same shape. I'll try to find an image to illustrate this

Here... Do you notice that even with missing vanes, the spike's shape doesn't change? Only the intensity does? That's why.

I'm not sure if I explained it in the best way in English, but it's understandable

When aligning the phone to the eyepiece, unfocus the star and check if all the vanes are visible in the secondary's reflection. If they are, move the phone until only two vanes are visible and take a photo...The spike will come out just like it did in my photo

That's why I got the tridaptor with 3-axis adjustment. It should arrive tomorrow.
It will solve this alignment problem.

[narrow plinth]

that focal length is godly

[half star]

excuse me how does an am5 hold a 12 inch 6500mm for 300 seconds

[lapis glen]

Ohh done this cluster before and I didn’t even know there was a pn there and sooner realized lol

[noble mountain]

No secondary mirror? so just the primary?

[worldly locust]

Single 5min sub

[mint depot]

https://tenor.com/view/holy-moly-gif-2379897567703251318

[half star]

so it's 6500mm but f4?

[lapis glen]

[mint depot]

Muhehehe

[lapis glen]

U steal my gif

[hardy field]

300 sec horsehead with an unfortunate 67% illuminated moon

[lapis glen]

Woah nice

Can’t wait to image this soon again

[hardy field]

300 sec exposure of flame and horsehead, this time without the moon

[lapis glen]

Woah

Big difference in contrast tbh

[zenith zephyr]

60s with the moon out

[muted bough]

and 5mins on RHo

[astral latch]

finnaly have something worth showing it aint much compared to you guys but im proud
5min ISO 1600

[sleek bear]

5 minute sub from bortle 3

and a 3 minute

[spring sluice]

Alrighty, a 900s Exposure of IC1805.

[lapis glen]

Wtffff this is a full image

Literally looks like it

☠️

[fossil basin]

lol

20 seconds

[spring sluice]

900s is a very long time lol

[lapis glen]

It is but still, quite crazy for 900 sec

15 mins

[heady forge]

180s

[neon valley]

180s with a tad bit of streching

[lofty snow]

500s somehow with my overloaded eq5pro which has extreme backlash problems

[plucky heath]

God damn

[astral latch]

(also EQ5 pro user) i recently found out that your best bet with guiding with severe Dec backlash is to give up and pollar align good enough so you can turn the Dec guiding off and forget about it, it does mean your target will slowly move away from your fov but if you are willing to check it every 2-3h to recentere it is absolutly fine
after pollaraligment with NINA 3PPA i was able to take 5min exposures with no trailing

[plucky heath]

Or you could just belt mod it

There are a few videos on how to do it unlike for the eqm35

[astral latch]

most of the backlash i found was in the worm gear belt would only change the backlash on gears before the wormgear

[plucky heath]

Oh well in that case that needs tuning you need to adjust the separation between the gears

If its too tight your gears can become sticky due to increased friction if it's too loose you will have play on your gears and thus backlash

[lapis glen]

Holy

Nice

[acoustic niche]

600s with az-gti & 72ed. Guided. Zwo 585

[fossil basin]

Cam?

That's great

[hardy field]

300 sec of half of the soul nebula

[acoustic niche]

Zwo 585

[neon valley]

Whats wrong with eqm35, when i got it my friend just put new grease and since then my average total rms is 0.50

[plucky heath]

Its a pain up my buttocks i can't get the stupid guiding working

The mount controller is weird when you press a key to slew sometimes it slews quite a bit after lifting your finger off the button

[plucky heath]

I'm guessing the uncooled version right

[acoustic niche]

Yes. I don't bother with darks. Flats and dark flats only. My location is prettyso recently my sensor temperature has been good between 2 degrees and 0.5 degrees celcus..
I did some testing with and without darks on the horsehead last, year and didn't see much difference (although I know it did).

[plucky heath]

Youll benefits from a peltier mod

[acoustic niche]

Yeah love that idea. Thought about it. Cheap enough and it's something I can do.

[plucky heath]

By the way get a double stage not a single stage double stage gets way colder than a single stage i have moded my own my camera and i get -13°C with sub optimal conditions

Also yes i do have the same camera as you the zwo asi585

[acoustic niche]

@plucky heath I may have to pick your brains at some point if you don't mind.

[plucky heath]

Nah i don't mind

[neon valley]

Weird, why just not use a laptop with N.IN.A and Green Swamp server for slewing... Also i managed to do 4 pull ups

[plucky heath]

Nina is a pain to work with and navigate its more complex and annoying than my school website

Also nice you work out

[neon valley]

To me N.I.N.A was confusing at the start but from time to time its really easy to use, give it a chance

[noble mountain]

2 subs both in Ha at 180s each. Redcat 51, 1600MM pro, Baader 8nm CCD Ha filter

[sleek bear]

RedCat 51

i forgot you got that white cat

[noble mountain]

Hell yeah! Whitecat is so nice

[rocky needle]

1x 600" sub each colour channel (RGB)

[graceful kraken]

2 minutes something on owl neb, test of duoband

[plucky heath]

How is that 2 minutes

[graceful kraken]

pay to win? maybe pay to lose im not sure how to interpret that

[plucky heath]

Like why is there no nebulosity and why is it so dimme for 2 minutes

[zenith zephyr]

Thats my 5s

[graceful kraken]

wack, guess dslr+thin clouds+full moon caused that?

[zenith zephyr]

I shot through moon too

Dslr is sensitive enough to oiii

Thin clouds is your only excuse

[marsh notch]

Here's my 100 secs

[half maple]

Ever stop to think what DSLR he's using and light pollution he's in? Your 715 is way more sensitive than most DSLRs.

Focal ratio should also be considered

[zenith zephyr]

Fair enough.

[marsh notch]

There are many factors

You cant just say that there is only one case where thats acceptable

[noble mountain]

Speaking from experience with a uncooled modded DSLR, thats about accurate signal

[graceful kraken]

its f4 lol

[plucky heath]

Ive seen film do better tbh the image looks extremely like it was taken on film

[plucky heath]

Are you using film

[half maple]

Considering he said DSLR i don't think it was film

Trust me, having used many DSLRs, some very old, some more recent, this isn't that surprising.

[marsh notch]

I thought you bought a cooled cam

[graceful kraken]

hasn't arrived yet

[marsh notch]

What cam? Ares C? Hopefully gets here soon. You'll see the difference greatly

[graceful kraken]

zwo 533

[half maple]

You using a 6" f4 newt?

[marsh notch]

Pretty sure carbonstar

So ye

[graceful kraken]

yea, carbonstar 150

[marsh notch]

6 inch f4 newts are peak

[graceful kraken]

yeah im suprised the 90d does that poorly apparently

[half maple]

Were there definitely high clouds present?

Also what bortle are you?

[graceful kraken]

dont remember 1st one but b7 or so

id say theres a good chance

(like 90%)

[hardy field]

Lobster claw 10 minute exposure, carbonstar 150, asi533 mc pro, l-extreme

[lapis glen]

brudda

ur a b1

hes a b7

i get the moon is there but still

[half maple]

Tyking is B1?????

[zenith zephyr]

*not

i got more lp

than that

im closer to b2/3

[half maple]

Tff

That deserves a mono cam

[zenith zephyr]

Wait. juust wait

[marsh notch]

Beatles reference

[neon valley]

Lucky, for the last year i have gone up from low b4 to probably b5-6

[zenith zephyr]

jeez thats terrible

[neon valley]

Finna go to court

[zenith zephyr]

Do it

[lapis glen]

Now it seems his sky is brighter damn

[lapis glen]

Do it

[muted bough]

I'd imagine snow would raise the bortle quite alot

[zenith zephyr]

Full moon plus snow makes my location a nice b5/6

[rose moth]

blinding from above and below

[neon valley]

Imma do it fr

[cobalt spear]

bruh. When it has a lot snow at my location night is day

[plucky heath]

Still better than my b9

How did u take images in NIR?

[sleek bear]

with a 685nm IR pass filter

[past hatch]

Which camera?

[sleek bear]

Player One Ares-M Pro

flying squid OIII 10 min sub (crop + star removal for visibility)

[quaint mist]

Am I the only one that thinks this nebula looks a little suspicious? Great photo btw lol

[sleek bear]

I had no idea that could show up in a single sub

How fast were your optics?

[dapper coral]

okay now THAT is crazy

[half maple]

I think he's F2

[woeful pewter]

yup, f.2.2 RASA11, and i got someone who lives in B2 to watch over my scope

[half maple]

Very nice

One of these days I may tackle squid

[woeful pewter]

and it's supposed to be clear pretty much all week, so i'm super hyped for the result

[half maple]

Maybe when I convert my newt to f4 along with a Nexus reducer for f3.

[woeful pewter]

i'm gonna get like 50-60 hours of OIII

[half maple]

That should be dope

[steady ruin]

I’ve done this on my Newt, works great

[sleek bear]

Ah that explains it

[junior bridge]

M46
114/900 + MI12
55s iso 400

1x55s iso 400 too

[sleek bear]

OOOOO

Left is raw and right is processed

Does my single 30 second at ISO 3200 count?

[ivory zealot]

oh bet i'm in

let me find some..

Single Halpha Filter 60 Second sub

[ivory zealot]

yeah as long as it's a single sub and not stacked

[neon valley]

Dayum

[ivory zealot]

yayy

thanks

Single Sub Carina nebula Hydrogen Alpha filter applied 60 seconds

[astral latch]

i don't get it how is it that much different than my dslr, when i take even 300s exposures i get stars on a gray background, there is absolutly no signs of nebulocity untill i ghater hours of data and after heavy processing there finnaly something starts coming out. i have a recent image of 26h on IC 405 and i bet one of you could get more detail in 60s. i know you guys use astro camera, mono and whatnot but it can't be litteralry THOUSANDS of times more sensitive than a dslr

[neon valley]

Bcs ur dslr isn't modified, it has an integrated Ha cut filter and Ir cut filter

[astral latch]

it's modified, i took out the IR cut fiter

[neon valley]

Lemme see a sub exposure

[astral latch]

90s on IC405

you can just about start seeing it but there is hydrogen all over that frame

(also that's a calibrated light frame not strait form the camera)

[sleek bear]

i meant more because one of them was processed

sort of

[neon valley]

Huh, weird. Maybe its beacuse the sensor is not as sensitive to those wavelengths i guess.

[half maple]

What sky conditions, scope, and exact camera are you using?

I see you have SW150/750 in your username but your sub has no diffraction spikes so I'm not sure

[astral latch]

i use those curvy things to remove diffraction spikes, aside from that
B7 and Canon 450D

[half maple]

Ahh ok yea, I used a modified Canon 450D early on too so I have a good idea of how it should perform.

Lemme see if I have some subs from my b5/6 skies with the 450d

Yea I took a look at some subs of equally bright nebulae with no filter and yours looks about right tbh.

It's a DSLR from 2008... Something like a 2600mc or even my already old 1600mm cooled mono cam will blow it away in terms of sensitivity.

[astral latch]

so i need to drop more money on that hobby..great

i gotta get a job in the summer

[half maple]

Something like the QHY minicam 8 (mono imx585) and included LRGBSHO filters is a very good value

899 USD iirc

[astral latch]

i don't get that much clear nights so i'd rather go for a one shot color camera

[half maple]

Cheaper than buying the cam I have with necessary filter wheel and filter set even used.

Which was already considered a budget mono cam

[half maple]

How many per year on average?

[astral latch]

oh god i don't know, but during winter i got like withrawl sympthoms after not seeing stars for 3 months

[half maple]

If you want to maximize data gathering you may want to look into a faster Newtonian/scope in general (or getting a starizona Nexus reducer) + monochrome camera. It might seem like OSC gets you an image quicker, but in the same about of integration time you spend on an osc cam, the mono cam will provide far greater results.

[astral latch]

i didn't think of that

[half maple]

my canon 1200D (slightly better than the 450D) VS my 1600mm w/ Luminance filter cooled to -10 C

Both 120s subs in b5/6

[astral latch]

that's a huge differnece

[half maple]

tbf its diff focal lengths but similar focal ratios

so ignore resolution differences

[muted bough]

Wtf

[silver flame]

But the 1200D one is still Bayered, no?

[half maple]

It is yes

I never had a cooled OSC cam so this is all I have to compare

[ivory zealot]

huh

[lofty snow]

me wondering why my 17h projects look like someones 4h project

[maiden temple]

Mono is still much better. You will get a better image regardless of clear nights.

[astral latch]

i would need filters witch are not very cheap either but than i remembered the Cuiv's video about a QHY minicam 8
small pixels mean i can do the highly zoomed in imaging that intrests me most but without a barlow that slows my scope down (and is aslo pretty crappy so it degrades my images) but at about 1000$ it's pretty pricy UNLESS the filter wheel is already packed with filters and i dont have to buy them. but i can't see any info on that anywhere, does anybody have the minicam 8 and could tell me if it has a full filter wheel?

[maiden temple]

It has different versions with different filters.

I’d get the Touptek package though. Only a bit more money and it supports standard filters.

[half maple]

It includes filters yes

[astral latch]

it's perfect
red is my daily setup
yellow is the same but with a barlow
and green is my daily with mini cam 8
and just for fun if i ever want to torture myself with guiding in blue it's minicam with a barlow
i think i know what to make money towards
thanks guys

i'll see you all here in a year 😑 drives off towards the setting sun

[lapis glen]

Just waiting for mine to arrive and my SHO filters to sell so i can get some LRGB filters

[junior bridge]

Are you still using the 1600mm? This single sub looks like my stacks

[half maple]

nah the 1600mm could never (maybe with dark skies and 1800s sub )

[half maple]

switched to a 2600mm

[hardy field]

I'm excited to see what I'll be able to get with this, just waiting on the camera to arrive 😄

[junior bridge]

I was looking for amp glow . Dream camera

[fossil basin]

why is there an arc

[pliant fjord]

It is a light leak.

It is quite unfortunate, but I have fixed it now.

[ivory zealot]

you lucky lucky man it's a shame your no longer rich after this investment

[noble mountain]

Someone change their mind about fracs?

[hardy field]

fr lol

[ivory zealot]

how much that cost in total?

[hardy field]

2.7k usd (including the camera, which isnt shown as it hasnt arrived yet)

[ivory zealot]

oh Jeeper

[noble mountain]

I assume camera is new at that price? likely a 294mm?

[hardy field]

585mm

[noble mountain]

Oh wow, majority of that is the filters cost then 😅

[hardy field]

yeah

[ivory zealot]

yeah

[hardy field]

the sho filters were about $100 more than the camera xD

[noble mountain]

Antlia moment

[ivory zealot]

Damn

the rig i'm planning is about be 1,395 USD on Avarage or with avrage prices

[hardy field]

nice

[ivory zealot]

so that's fun

this is the FOV i'm working with on the rosette soooo

[hardy field]

I like it

[ivory zealot]

yeah!

[hardy field]

Mine will be similar, it should make for a decent computer or phone background image

[ivory zealot]

yeah! we should move to astrophotography chat though

[hardy field]

ye

[ivory zealot]

let's move over there and contuine this talk shall we?

[hardy field]

Saw a guy call that region the skateboard nebula or the skater nebula, can’t unsee it since

[hardy field]

[noble mountain]

Looks like a little skater on a half pipe

[hardy field]

I tried imaging it with my 533mc with a full moon and a cheaper duelband filter in the past, it turned out trash for my liking

[noble mountain]

well it’s gonna be different this time

[hardy field]

Fr, I'm going to enjoy this new camera and filters alot

[noble mountain]

Which cam and filters? IMX 571 and Antlias?

single 10 min sub in HA from bortle 6

[raven birch]

Because it's the same target

https://tenor.com/view/the-universe-tim-and-eric-mind-blown-mind-blown-meme-mind-explosion-mind-explosion-meme-gif-18002878

[mint depot]

he means the SNR difference given the integration time

[raven birch]

i know . i was just joking

[raven birch]

but i think he sent them the other way around. the 5min has more SNR than the 10min.

[mint depot]

if you look at the cygnus wall you can see browis' has more detail

[raven birch]

Better guiding?

[mint depot]

i wouldnt say so, the RASA is a f/2.2 lightbucket. leroy's scope is f/4 i think

[raven birch]

ahhh... now that makes sense. i thought they used the same telescopes

[woeful pewter]

Yup, cause mine was also taken from Bortle 6

[half maple]

Actually the difference is quite noticeable

[heady forge]

Tyking's 300s Ha sub with no astro dark

Dude's got more snr than me in 2 hours 🥲

[slow blade]

why so soft?

[heady forge]

Are you just going to completely ignore the fact that the outer shell is showing like that in a single sub

[slow blade]

signal is decent - just very very soft

[heady forge]

He's simmply using a newt not a frac which lets him see some nice details after applying blurx

[slow blade]

brother what

blurX shouldnt be used exclusivly to acheive details

it should NOT be relied on

[heady forge]

If it works it works :)

[woeful pewter]

are you sure it's soft, and not just overstretched?

[slow blade]

something is wrong in his optical system, seems like a mix of guiding/collimation

[slow blade]

prob a mix of both tbh

[slow blade]

L mindset

[heady forge]

His guiding is sub 0.5" and his collimation looks decent

[woeful pewter]

tho stars are kinda weird

[slow blade]

collimation is NOT decent

stars are flaring

[heady forge]

He's at 1000mm of fl and has 2.9 um pixels

[slow blade]

so?

[heady forge]

Oversampling?

[slow blade]

that doesnt excuse the mis shapen atars and why its so damn soft

[heady forge]

Its soft because hes oversampled and yes maybe his collimation is indeed bad but whatever

[slow blade]

at .6"/pixel it should not be that soft

[mint depot]

Yeah that telescope isn't collimated properly

You just have to look at the stars as nexy said

[noble mountain]

Deconvolution is to help correct the atmospheric distortions and/or any optical errors. And Deconvolution actually still has a much stronger/better effect on data that is near perfect, good seeing, spot on collimation. I would avoid relying on it for details and focus on getting better data (:

[half maple]

Bro what, I know it's out of colli, but it ain't as soft as your making out to be lmao. Looks close to 2". Very similar to my Ring.

[slow blade]

look at those stars g dawg 🙏

[half maple]

I acknowledged that?

Blud is acting like he should have perfect seeing

[half maple]

Signal is pretty dam good

The shell was def less noticeable for me.

After bX and dsnr

A couple hours iirc

[noble mountain]

Big stars doesn’t mean details are absolutely cooked tho lol

Sampling has a big play

[half maple]

Usually goes hand in hand tho tbf

[noble mountain]

Ahh I mean look at Lyaphines data for the master processor comp, that was sharp asf but the stars are huge and really soft

[half maple]

Yea diff systems handle brighter stars differently

The stars closer in brightness to the target are more so what should be compared. Also, something like bad collimation is going to be more evident in pinpoint sources of light rather than diffused sources such as the target your shooting.

[half maple]

[half maple]

It's taken already

[neon valley]

At least i tried

[viscid palm]

Well thanks, you ain't so bad yourself

[cobalt spear]

and which one? Name?

[half maple]

Astro-Tech AT8N

Bad design, I got it for a steal and a moonlight focuser included so I went for it.

But didn't realize how dumb the colli system was

The secondary mostly can't be rotated

The very fine rotation adjustments one might need to perform cannot be

My plan was to mod it and replace allat but the tube size is smaller than my CNC spider.

I have a fix for it but have yet to implement it.

[cobalt spear]

bruh

how is the image quality?

[half maple]

some current projects with it

most 8" f4 mirrors out there are gonna be fine, it's the OTA and hardware that really make a difference at this price point.

[hardy field]

[half maple]

Is this supposed to be arcseconds?

There's no way

[heady forge]

no

have you ever measured it in pix using subframe selector

i consider anything below 0.48 to be good (the bigger the value the more trailing there is)

i mean i dont even know in what units this is

[half maple]

No I always use the fwhm eccentricity script included with pix

Specifically on the master light

It gives fwhm in pixels and you multiply that by your pixel scale.

It's a more meaningful measurement

[heady forge]

yeah the eccentricity is quite bad

so the fwhm in arcseconds is 2.8"

[heady forge]

but what exactly do you mean by that?

the results are pretty much identical

[half maple]

I just meant compared to the eccentricity value you were using. But yea in general fwhm means more to most people. It's more commonly used.

Microlensing

Most sensor coatings aren't optimized for NIR or UV

[opaque finch]

ohh i see

quite cool

so would the pattern look the same/similar with a refractor?

[wise shore]

yea it does i have a photo from mine somewhere. its light bouncing inside the camera both inside the window and inside the microlenses on the sensor itself

[woeful pewter]

But that also means it's purely an OSC thing right?

[wise shore]

nah both mono and color can have these. The bayer matrix is typically applied first then microlenses ontop. Its also strangly not all microlens array cameras have such issues. ASI1600 has it and ASI2400 has it. 2400 gets it way worse in Ir and 1600 gets it about the same in all wavelengths if I remeber correctly.

[woeful pewter]

Dang

Mono is not completely immune to problems then

[wise shore]

mono is 100% not immune. I get way more real world problems with it then color. the price I pay for more light

[woeful pewter]

Yeah that's facts. OSC is the easy way, but not the best

[half maple]

The 533, 571, etc have it too in the far ends of the spectrum.

But yea hella worse on older sensor tech

Or at least the ones you mentioned, not sure about ccd's.

[wise shore]

I should test CCDs I got a 8300 and a 8050 laying around

8300 should be one with microlenses but I'll have to check the 8050

[wise shore]

I've never actually seen it in 571 now that I think about it. I should really run some tests. Heres one deer lick galaxy sub at 1000nm+ and the curve of camera.

I'll do a star test next clear night. this got me curious

[neon valley]

The K8300 is a good sensor, realy good at picking up faint details. Also i discovered that the optimal exposure time for those kind of sensors need to be 10-15min long

[worldly cove]

I only see significant microlensing on bright stars with my 533

[half maple]

Nothing special about it really, it's just way worse than new CMOS tech lol.

[neon valley]

Cmos are better to a certain point, still mono ccd sensors are quite up to date with the performance it gives and the pixel size

[half maple]

The kaf 8300 for instance has 25k well depth and a QE of 50% so not really up to date.

CCD's can certainly produce good results in the right hands.

Def not comparable to new IMX starvis sensors

I wouldn't ever recommend someone going out of there way to purchase one...

I still think the 8300 is cool because it was, iirc, the beginning of affordable CCD cams for amateur AP.

[neon valley]

Thx for the detailed info, i still manage to get good results with it

[wise shore]

my 8050 is maybe a tad worse than my asi1600mm. sony starvis is wayyyy better than either. sad how CCDs are dying but I’m very happy with shooting at f10 and it actually being a sensible option with modern cmos

you’d be shocked at the difference between the old kodak ccds vs starvis 1 and the imx571

[neon valley]

Yeah, this is my latest work with the 8300

[half maple]

Why a .dng?

[neon valley]

I tried some other formats wait i got a PNG i think

Compression💔

[plucky heath]

I see a dust spot

[neon valley]

I know, i cleaned the filters multiple times and the sensor glass... and its still there

[plucky heath]

Yeah i feel you i can't get rid of my
dust spots either everytime i clean a new one manages to pop up but they're usually on the camera window or if not they might be inside the camera housing You can see that the dust spot is very small and almost in focus meaning that its located right on top of your sensor

[neon valley]

I cant even see the dust spot on the glass and somehow its there😭

[plucky heath]

No not on the glass

Below the glass

Inside the camera housing

Directly ontop of your bare sensor

300 sec sub ha

[half maple]

Dope

[neon valley]

Ill be damned

[plucky heath]

You cloud try and open it to get rid of it but uhh use a blower if you are going to do that also be fast

[half star]

scrape it off easy solution

since when did you get mini nerd

[plucky heath]

Since like a few months ago

[half maple]

600s SII and Ha subs

[cobalt spear]

goated

[full cedar]

300 sec sub Blue on IC 63

[opaque finch]

5min on Ha, new setup

did Sii and Oiii as well, so this is a total of 15mins. the mono equivalent of a single sub?

gonna run a little 3h sequence on it tonight

[mint depot]

Holy denoise

[opaque finch]

haha yeah mb, single sub S and O aren't enough to process without some deepsnr

raw subs for each

[mint depot]

It's gonna look awesome

[opaque finch]

yeah, lookin forward to it

[opaque finch]

12x the data of this hot mess

also im breaking it 2:5:5 ratio cuz Ha is so much stronger

[mint depot]

It's the cats paw nebula right?

Single 5m lagoon nebula shot quickly processed

[half maple]

What happened to the white point

[raven birch]

You know it's white enough when you flip the bit back to black

[queen scroll]

I just did a big S curve to see what was in the image

Didn't really care if that clipped the cores

I've collected around 10hrs in broadband and 14hrs in duo narrowband so hopefully the results looks good

[half maple]

Weird, wouldn't have expected that to happen from just an S curve

[queen scroll]

It was a big one

Just one point towards the white point dragged to the top and one point dragged to the bottom

Also did a background extraction and colour calibration

But for one shot on a DSLR it looking great imo

Does anyone here have an idea on how I could mix the broadband and narrowband together since I haven't done that before

[noble mountain]

Funnily enough my old DSLR actually used to do this when it was clipping XD didnt clip like standard cameras and go pure white, but instead a pink or blue and almost look duller than anything else lol

[queen scroll]

Mine does the same lol

Nina saves the images pure white for some reason

[junior bridge]

Timelapse with my last m27 subs...
Subs of 30s at the beginning and 55s at the end (On the first night I captured with 30s by mistake. I only noticed at the end of the night )
114mm F8 + Xiaomi 12
Bortle 4 + lots of red lights that my friends wouldn’t turn off
The jumps are just my manual dithering.

Too bad I live in the northern

[half maple]

Southern hemi is fake

Propaganda

[muted bough]

Yeah, he's right I'm a fraud sorry I've been keeping this a secret for to long

[cobalt spear]

Huh

Everything northern hemisphere. You are right, thats makes sense
