Untracked Astrophotography

[nimble lintel]

But still happy with it

[dusty gull]

I have 3 hours of widefield data to process

Some stars over the mountains reflecting in a lake

[little prism]

niceee

[lucid badger]

I dont know if its the orion nebula but it was taken on a 60x900mm

[grave rapids]

that is indeed the orion nebula

[lucid badger]

[lucid badger]

You dont know how hard it is to track it on a 5yr old 60x900 eq mount

[grave rapids]

i might know better than you think ive tracked a celestron powerseeker 127 eq, probably 7 years old, rusty. absolute nightmare.

[lucid badger]

Ok you kinda know it lmao

But this is an F15 telescope, you dont know what are you tracking untill you take a short exposure pic

[grave rapids]

oof

127eq is f7.9 so its bad but not f11 bad

[lucid badger]

Yeah, never buy a telescope with 60mm apperture

[grave rapids]

i mean the 60mm isnt really the problem, small aperture is fine for widefield deep sky. the problem is 60x900

[lucid badger]

Yeah....

If it was a 60x600 it would be much better

[grave rapids]

or maybe 50x600

or maybe 51x250

[neat scroll]

quick test, 1/5 of my total data

[dusty gull]

My M51 data starts to get interesting!

30min of data on 2 nights

Its quite a hard target untracked because there's almost no useful star

Had to reject half of the frames...

[viral rivet]

pretty nice

[dusty gull]

First process, I'm not happy with it but I don't have the time to do better

[radiant osprey]

whats camera, bortle what?

[radiant osprey]

orion nebula, 15 min untracked

without stars

[viral rivet]

nice

whats your equipment

[radiant osprey]

700x76 telescope with zwo224 camera

[viral rivet]

the shot is incredible for this equipment really nice

[radiant osprey]

ty

[dusty gull]

Asi 224mc bortle 3

[orchid obsidian]

So looking forward to the next clear skies to continue my mission of capturing the Orion nebula with my humble kit! You guys are amazing.

[viral rivet]

scope?

[grave rapids]

i believe its a skywatcher heritage 130p

[viral rivet]

sweet

[dusty gull]

I got 2h30 on orion

Will be hard to process

[viral rivet]

how much real time did it take

[dusty gull]

Only 3 hours I think

[viral rivet]

thats great , with my phone, it takes 1sec for 1/2sec exposure so if i do astro for for 3hrs i only get 1.5hrs data

[dusty gull]

Yeah I'm pretty lucky with my setup

It's relatively easy to use for untracked ap

[dusty gull]

130g of data

[strange seal]

rookie numbers

[dusty gull]

You have an 8 times bigger sensor

This is equal to 900 gb with your cam

[strange seal]

[dusty gull]

Very work in progress

[upper pasture]

ooo

looks nice

[neat scroll]

holy shit nice work

i like how you can see the dark nebulosity on the top very clearly

[dusty gull]

Yeah and hopefully it will get better (this is just autostretch, no denoise and 1/3 of the data)

[neat scroll]

🙏 🙏

i'm sure it will

[dusty gull]

Also I have more panels (this is a mosaic)

[neat scroll]

oh nice

how many?

[dusty gull]

3 but they are not very good so I'll crop quite a lot and there won't be a huge difference with the one I sent

[nimble lintel]

My mind keeps om being blown by your untracked ap

Looks incredible

[gaunt meteor]

I got a tracker so I’m leaving this chat, but this is my last untracked photo, bye bye

[lucid badger]

Some orion nebula photos i made tonight

[dusty gull]

Close to be final

I'd like to manage the gradient a bit better and there's some improvement possible on the core

Also noise isn't perfect

But I'm quite happy with it

3 hours of acquisition and almost 15 hours of processing

[radiant osprey]

Whats scope?

[radiant osprey]

what software for processing ?

[dusty gull]

Heritage 130p and asi 224mc

And I used siril, photoshop, AstroDenoise and rawtherapee

And Microsoft ICE for the mosaic

[radiant osprey]

can u use siril for SER files to align and stack ?

[dusty gull]

It's what I did

[radiant osprey]

thats a very good result from 224 camera

untracked right?

[dusty gull]

Yep

200ms subs

[gentle birch]

oh wow

[lucid badger]

I just dont know how the asi224mc its soo good for that price

Is like dark magic

[neat scroll]

my man this is amazing

[visual pecan]

How do I know that it is time to realign with my target when taking pictures on a tripod?

Sorry if the answer is obvious to you.

[static cape]

Personally I like to keep the target a little bit centered. I think it's easier for stacking software to stack (but I don't know if that's true..) but it depends how much you are zoomed in then..

[tight jewel]

untracked 80/900 refractor with phone

[visual pecan]

So I can allow my target to drift for a bit before realigning?

[static cape]

Yes👍

[viral rivet]

guys thinking about star trailing, should i take 300ms subs for orion

[strange seal]

https://docs.google.com/spreadsheets/d/1tSEbji6V4rYz81COybiD5LWaekULIQReJy7kZCxQy78/edit?usp=sharing
set trailing to 2 px

[radiant osprey]

180ms starless 20 min exposure untracked bortle 9

[viral rivet]

ok thanks

[viral rivet]

nice

also what fl

[radiant osprey]

what is the fl ? sry am bad at this things

[viral rivet]

focal length

[radiant osprey]

700x76 asi224mc cam

[viral rivet]

really nice image with this equipment

[radiant osprey]

ty

[viral rivet]

which stacking software?

[radiant osprey]

astrosurface

[radiant osprey]

ser files

[viral rivet]

nice ill try it too (i have been getting bad results stacking using dss and siril)

[gleaming walrus]

Got a good LMC data from where I stayed last day

Horizon was good and LMC was visible a bit with naked eye

[little prism]

wow that is gorgeous . Goob job!

[upper pasture]

Nice, What did it look like naked eye? I'm northern so i dont get to see it lol

[neat scroll]

lmc looks like a dim cloud in the sky

[neat scroll]

tweaked a bit my keyhole pic, really like it!

[gleaming walrus]

I am at north too,

But it was visible like a smudge in sky with naked eye

Single sub

[radiant osprey]

can i use NoiseXTerminator without PixInsight ?

[strange seal]

its in photoshop too

[radiant osprey]

How i use it on ps

[strange seal]

you have to add it as a plugin

theres info on the site

[radiant osprey]

how long is the free trail ?

[strange seal]

not sure

[lucid badger]

You should buy a coma corrector btw

[lucid badger]

I dont have the money even to buy a 20x40mm scope

[neat scroll]

no i mean i don't have any

[lucid badger]

Same

[neat scroll]

i'm saving up to buy a cheap ccd, currently using my phone for imaging

[lucid badger]

I'm trying to collect money asking for donations, i've collected exactly $0 (i'm a minor)

[lucid badger]

asi224mc

That's probably the best you can find

[neat scroll]

yeah or perhaps a mars c or uranus c

[burnt bay]

Mars C

[gentle cipher]

Ceres C > ASI224MC

Same sensor, good quality, 25% cheaper

[neat scroll]

[burnt bay]

Cigar Galaxy

And a scuffed asf Whirlpool

[static cape]

Nice! What equipment and iso/shutter times?

[burnt bay]

6” dob, PO Mars-C cam

Cigar settings were around 280ms, binning x2 and I forget the gain

Whirlpool was like 400ms, binning x4

[livid wing]

How many exposure?

[burnt bay]

Around 500 frames, just a few minutes of data

[static cape]

First try on flame and horse head. About 15 mins

Going for a good edit tomorrow!

[radiant osprey]

hubble nebula, (untracked) bortle 8 with 700x76 scope and asi224mc camera 25 min exposure .

[sharp heath]

Very nice

[radiant osprey]

ty

[ornate spade]

you got THAT, in b8 with a 76/700 reflector??! very very nice.

[radiant osprey]

Thanks<3

[static cape]

How much free space do you all have for stacking? When using Siril I need more than 700 gb for the process. Recently I bought 1 TB but it's not enough apparently?

[tidal tide]

siril used an obscene amount for me too, just gonna use DSS

[static cape]

Alright should probably try that out for stacking too then.. last time I used DSS it kept crashing and shutting down in the last stage tough

[dusty gull]

Do you use scripts?

[dusty gull]

For me dss take more space than siril

And is a lot slower

[strange seal]

Yeah it depends on settings lol.

[static cape]

no did not try it out yet

I'm about to bc DSS keeps stopping/crashing just before finishing stacking

[static cape]

Orion again, 15 mins. Tried to edit it with a bit less saturation and played with layers in Gimp and the core is less blown out. Trying to stack both sessions now to get 30 mins of data!

[short galleon]

The image below was taken using my sony a6000 with a 50mm f/1.8 lens with less than 10min of integration from a bortle 3.5

[radiant osprey]

some edits on hubble nebula (untracked) b9 ,on gigapixel software

[tidal tide]

not topaz noooo

[static cape]

Is topaz that bad? Never used it tough

Tried it out in a free version with the watermark. Had the feeling they added extra noise in the before picture

[tidal tide]

it's not meant for astrophotos, they can generate fake detail and can/will make the photos worse

[static cape]

Ah I see

[radiant osprey]

why

[tidal tide]

.

[radiant osprey]

is there a better alternative ?

[radiant osprey]

than topaz

[tidal tide]

for denoising there's noisexterminator, astrodenoisepy and a whole bunch of other techniques for it

[radiant osprey]

astrodenoisepy doesnt work for me

[grave rapids]

i mean pretty much any traditional denoiser is better than topaz

[radiant osprey]

and noisexterminator doesnt work with me

is that noise in the background because the mirror is not aligend

[static cape]

Does GIMP has it build in? Guess not right?

[tidal tide]

i remember rawtherapee had good denoising, you should ask @timber folio about it

[grave rapids]

no thats because you need more data

there will always be noise

[radiant osprey]

thats 45 min

[grave rapids]

more data = less noise

if you want less noise you need more data

[radiant osprey]

i know but this is a foggy noise not rgb noise

[grave rapids]

still. i mean if you dont take darks those may help, but nothing else can fix noise

[dusty gull]

Or faster lens/scope, better sky, longer subs and more sensitive camera(better quantum efficiency and read noise)

But you'll alaways need as much data as possible

[radiant osprey]

which cameras better for deepsky (planetry cameras) playerone cameras or zwo

[strange seal]

player one generally

i have a Uranus C and its great

better than the ZWO version

[radiant osprey]

also the rest ?

[strange seal]

i think they are generally more stable and work better yeah

what camera are you considering

[radiant osprey]

like Neptune-C II

uranuc c in the future

i have now zwo224

[strange seal]

unless you need the neptune for something special def save for the uranus

its hardly an upgrade from the 224

but the bigger sensor on the uranus makes life so easy

its also a nicer sensor overall

[radiant osprey]

yeah small sensor with untracked with bortle 8 yes baby big shit

[strange seal]

i used a IMX290, same size as 224 for planetary and some deep space. i lost 10 years of my life

[radiant osprey]

wow, lol

[strange seal]

uranus c best mid range camera

these ones are untracked

[radiant osprey]

u use it with cooled or not

[strange seal]

nope

top lot of images are with roki 135

bottom are with 8" dob btw

[radiant osprey]

wow man, i will buy it

[strange seal]

great, you wont regret it

whats your scope youll use it with?

[radiant osprey]

700x76

[grave rapids]

might want to replace that

[radiant osprey]

why

[grave rapids]

it has a long focal length and a small aperture, so its slow. that means it doesnt have a lot of light gathering power. and its also probably cheaper glass that will give you more problems down the line.

[radiant osprey]

so u mean when i capture something i need a double more date because my telescope is not good for light gathering power

[grave rapids]

yes. there will also be problems with all your stars having violet halos.

[radiant osprey]

my telescope is a reflector i dont thing they will give me violet halos

[grave rapids]

oh sorry, i assumed that small aperture would be a frac. youll have coma then, where stars are stretched out on the sides.

[radiant osprey]

thats on the refractor telescopes

stretched stars on sides

[grave rapids]

no thats on newts

well actually its on both

[upper pasture]

how much is it?

[radiant osprey]

400$

[neat scroll]

you're on fire 🔥🔥🔥

[dusty gull]

[tight jewel]

how

[hallow tapir]

20min untracked

[dusty gull]

Planetary cam+b3+lots of subs

[strange seal]

pretty much

big dob

[tight jewel]

Amazing

[dusty gull]

Yes too

Fast dob is more important though

[radiant osprey]

what u mean by fast?

[dusty gull]

The focal ratio (focal lenght/mirror width) has to be small enough

The smaller it is, the brightest the image is

[radiant osprey]

my telescope fl 700/76 is it bad ?

[radiant osprey]

give me a example for good focal lenght that is small mirror width

[dusty gull]

Kinda... Its is 4 times worse than f5 for example

I feel like f6-7 is the limit

If you can bin your camera it's different

[dusty gull]

What do you mean by small? Also what budget? My scope is 130/650mm and it's pretty good

[radiant osprey]

what is the small enough?

[dusty gull]

As I said above, I'll f6 or 7 but it very much depends on your bortle, pixel size, ability to bin or not and target...

[radiant osprey]

and is it possible to avoid the bad of the telescope the (fl) with good camera ?

[radiant osprey]

polaris star last night , its the favorite star for people they dont have a tracker mount like me because it dosent move , bortle 9 , 45 min exposure , asi224 cam

[radiant osprey]

and here is sirius

[viral rivet]

it has a f ratio of 9 so its good for planets and really small DSOs with enough integration time (btw I have a 114/900 f ratio 8 with this i can get orion in frame perfectly (in my pfp))

[viral rivet]

REALLY NICE

[radiant osprey]

what camera u use?

[viral rivet]

phone

[radiant osprey]

nice

[viral rivet]

what software do you use to stack the images I cant get to stack images with very few stars

[radiant osprey]

i capture a SER files then use astrosurface to stack the vid to be a stacked pic

[viral rivet]

ok thanks

ill try too

[radiant osprey]

i dont know if it work on phone

[viral rivet]

ill try to convert img files to ser in pipp and then load it in astrosurface

[gentle birch]

dinesh is always coming out with bangers idk how

[strange seal]

Gacrux, Mimosa, Alpha Centauri and Jewel box cluster.

[static cape]

having a hard time processing pleiades. but here is something

a lot better than this one tough, about 10 mins extra exposure!

[gleaming walrus]

What 🙈,
I need to improve a lot 😅

[gleaming walrus]

Was captured from Northern Hemisphere,
Location: Vattakanal, India.
10.2°N

550 subs, each of 8 secs long
F2.0
ISO 6400

Forgot to add details yesterday

for this one I used stack of 10 images and added the LMC above it matching the star patterns manually,

This is the exacts size of LMC on a 50mm (little bit cropped the top to get 16:9 aspect ratio

you can see the trailing in the trees due to stacking, but it was not prominent so I haven't touched that

[gentle cipher]

thats genuinely amazing

and beautiful

ive never seen the LMC in person and I sadly don't think I ever will get to. but this image gives perspective to that galaxy. its a beauty

hard to describe this image but just know i love it

[gleaming walrus]

thank you @gentle cipher
It was my first time witnessing it, was able to spot with naked eye

[gentle cipher]

really? that must have been so cool

[gleaming walrus]

not prominent but it looked like smudgy big star cluster

[gentle cipher]

what bortle is this from?

[gleaming walrus]

Yes, I was shouting 🤣

[gentle cipher]

i would have too

[gleaming walrus]

most probably a 3

[gentle cipher]

have you posted in #deep_space_pics ?

[gleaming walrus]

no

will post there

[grave rapids]

Why not? I mean a vacation to Australia is something that someone could reasonably save up for, depending on how much they make ofc

[gentle cipher]

eh you're right I might

[gleaming walrus]

That'll be great

[dusty gull]

This is really nice
Honestly I often find LMC pictures boring and not well done but this one is really lovely and it is untracked...

[gleaming walrus]

Thanks a lot 🙌
I like LMC but couldn't try for a long time but got an opportunity 😅

My 1st try, this was near my home, some 30 to 40 kms away

[dusty gull]

Yeah quite an improvement lol

[mental sky]

Orion : 2.5 minutes exposure (150*1s 1600 iso from my iPhone 12 through my powerseeker 60eq)

[static cape]

Another edit on pleiades above. Nice to see the progression. Less than 2 months apart I guess!

[gleaming walrus]

most probably I captured that LMC through a B8 sky I think 🤣

The recent one was a B3 to 2 so It had details

[marble kite]

shot this last week with full moon

[gentle birch]

acquisition? gear?

[marble kite]

5h18m with nikon d7000 (stock)

2.5s exposures at 50mm

[gentle birch]

that's absolute nuts

the dedication is crazy! I've only done an hour for my longest untracked session

[marble kite]

thanks!

[gentle birch]

too bad it was during a full moon though 😭

[marble kite]

yea at the end of every session the moon came a bit to close and you could clearly see a gradiant of the moon

it was so awfull

[gentle birch]

I assume that's why you clipped the background somewhat

[marble kite]

yea

[radiant osprey]

this orion taken in bortle 9 with full moon (untracked) with 55-250 canon lens with asi224 cam, only 45 min exposure

[little prism]

I don’t think my seeing was this good before. Even my phone could see Orion which is unusual since it is a iPhone 7. I can proudly say I imaged Orion with my phone

feels awkward to post this but I thought it was kinda cool

[gleaming walrus]

Wow nice,
I haven't went for that much hours but I failed to get much details from B7 and I purposefully kept F4.0 ☠️
So Lesson learnt
2 and half hr of data wasted

[burnt bay]

Ghost of Jupiter Nebula tonight

Insanely bright in the live view

Visual was pretty awesome too, very obvious blue color

[burnt bay]

Sombrero

[static cape]

How much Integration time is this?

[radiant osprey]

whats camera

[strange seal]

ASI224 from memory

[viral rivet]

took this with my phone and a cheap 70/300 frac 200 x 1.5s shots (stacked in sequator)

[burnt bay]

Player One Mars-C, imx462 sensor

[burnt bay]

Around 1k frames of 250ms I’m pretty sure

Not a lot

[static turtle]

My god how, untracked and 2.5 shutter and 5hrs that is mad!! Props to you man thats some dedication right there

[marble kite]

Thanks!!

[visual pecan]

Nice progress! What settings did you use on your camera?

[static cape]

It's on a Nikon d5300 with a skywatcher 80/400 in front of it. 1 second and iso 3200. Upper one is 20 mins and the lower one 15 I think

Also posted this elsewhere but kinda proud! Managed to do this from zero knowledge about dso to this in a couple of months. What object is next?

[upper pasture]

M81/M82?

Nice galaxy pair, relatively easy to image

[static cape]

Ah yes last time I tried I couldn't find it. No finder scope and so, someone tipped me about plate solving. Any software you can recommend?

[marble kite]

I mean #🤖-ask-a-bot can help really good

[tidal tide]

https://nova.astrometry.net/upload

[static cape]

Oh wow didn't know this was a think

Thanks both

Also bought a cable and installed Nina out of interest

[hallow cove]

Thinkin about doing widefield untracked with a dslr + lens

what are our thoughts about that

[ornate spade]

Good idea, I tried it and its fun. Results will depend on your lens focal length, aperture and light pollution. You can calculate the maximum untracked time using the calculator in the pinned message.

[hallow cove]

I'm in b5 and the lens I'm looking at is 28-80mm

[ornate spade]

I took this with my 600D in the same bortle with I think same lens at ~67mm F5.6 30 minutes of total exposure. definitely possible. There is significant chromatic abberation through: the stars are larger in the blue channel.

[hallow cove]

Was gonna get a 500D since that's only thing in my budget really

[upper pasture]

This was taken with a 600D, similar camera, in a bortle 4, using a similar lens (18-55mm). Only 4 minutes of data.

I changed to B&W, but you can get some nice photos using a widefield lens, camera and a bit of time

[hallow cove]

shall I just go for it then

[upper pasture]

Do you have a computer?

[hallow cove]

I have a desktop

[upper pasture]

Can you install software?

[hallow cove]

no laptop but might convince my dad to lend me his

[hallow cove]

most likely if I can deal with deleting some of my checks notes 562gb of memes

[upper pasture]

damn lol

[hallow cove]

ok it's not just memes but like

562gb of videos

[upper pasture]

"videos"

[hallow cove]

mostly memes, some are me playing geometry dash

[upper pasture]

but you will need to install the astro software, one for stacking multiple images, and one for processing the images

oh you werent joking

damn

[hallow cove]

I have dss and siril installed already lol

[upper pasture]

ah okay good

SiriL is a really good free software for astro lol

Well, as you have that, I would definitely go for it

[hallow cove]

500D + 28-80mm f/3.5-5.6 II

£128

[upper pasture]

This was captured untracked, using a 600D camera, and a 55-200mm lens (shot at like 70mm)

very noisy, but oh well

I spent about 230 quid on my 600D, 18-55mm lens, and 55-200mm lens

[hallow cove]

I can do darks tho to lower the noise right?

[upper pasture]

yes, I think darks and biases remove a bit of noise

and make sure to do your flats too

flats help with vignetting and remove dust spots

[hallow cove]

ye alright

I don't actually have a credit card (under 18) so I gotta go get my dad to buy it then pay him back

[upper pasture]

Also, some star trails taken from my backyard. taken at like 50mm

So yeah, there's a lot you can do with a widefield lens

[hallow cove]

Might get a star tracker for my bday in july so that could be an upgrade path

[upper pasture]

I would recommend trying star trails first, as they are easy to do, and dont require loads of times

[upper pasture]

Nice, a star tracker will definitely help

Have you seen the milkyway core at all recently? It's slowly rising above the horizon during the dark hours of the morning

[hallow cove]

had clouds for ages so haven't seen anything

I mean it was clear just after sunset yesterday so I saw orion nebula but that was about it

[upper pasture]

Yeah, I've had a lot of clouds recently

Orion Nebula is a cool target, I presume you saw it naked eye?

[hallow cove]

I have an 8" dob for visual

At 75x mag with uhc filter it's rather stunning

[upper pasture]

Oh nice

I currently only have a small 2.3" refractor which I bought for 20 quid, but It's shown me some really cool stuff

[hallow cove]

I convinced my parents that dark skies are cool so in mid july we're going on holiday to b2

[upper pasture]

Nice, Never been to a bortle 2, but I'm sure you'll enjoy it

[hallow cove]

And we're staying in a cottage rather than camping so much more space in the car

so might fit the dob in there as well

[upper pasture]

Is the B2 in the Uk or are you going abroad?

[hallow cove]

It's in ireland so technically abroad but still speaking english

[upper pasture]

Ah nice, There's some Bortle 2/3s here in Wales too, which is cool. I know Scotland has a few Bortle 1s

[hallow cove]

It's fun looking at the uk on a light pollution map because oil rigs in the north sea show up

ok im actually buying it now

just gotta hope the shipping isnt too high

£6 shipping

just out of my budget

unless I can find some cash

Now I have like 3p in my bank account and 50p in cash

[lucid badger]

Tooked with a samsung a53, 10 second exposure iso 3200, mount? What is that, just using my Skywatchair alt/az manual and two shin guards

[dusty gull]

I finished gathering m81 data, finally

21k frames

3 hours of integration

[burnt bay]

This is gonna be a banger

[static turtle]

Damn

[dusty gull]

Not sure 😅

It's quite faint (for untracked) and I have huge walking noise issues (that I don't have with other targets, no idea why)

[grave rapids]

3 hours untracked is crazy

the most ive done is two but that was with a dslr, telescope + astrocamera for 3 hours is super impressive

[static turtle]

Fr

[hallow cove]

Will stacking programs be smart enough that I don't need to re-aim the camera after every few pictures?

[ornate spade]

yes, as long as the pictures share at least 8 stars DSS will be able to stack them together.

[tidal tide]

i still wouldnt let the object drift out too much

[static cape]

Indeed, at 400 mm I recenter about every 30/40, 1 second exposures

[dusty gull]

Haha yes it was kinda long

[dusty gull]

And with my crappy weather...

I swear I had more clear nights in one month last summer than in this whole autumn/winter

[hallow cove]

that my friend is called the seasons

[dusty gull]

Well I hate seasons

[hallow cove]

I'm going bortle 2 in summer

convinced my parents that it's a good idea

[dusty gull]

Ohh

[hallow cove]

better be clear

[dusty gull]

But seriously its usually not that bad

And almost all clear nights where during the full moon or when I couldn't image

[hallow cove]

My local university does astronomy open evenings in winter

they said in the 23 years they've done it this was the worst year

still get interesting lecture so it's fine

[dusty gull]

Oh cool

[hallow cove]

it is now too light in the evenings so they have ended

[timber folio]

dead

[burnt bay]

so real

[gentle birch]

I guess everyone bought a tracker

[burnt bay]

one day

[tidal tide]

not yet

[void condor]

I did, sorry guys I’m sure more will come

I mean, these are my finished untracked, dslr images

And I’ve got another one too but I’m not done editing it

[burnt bay]

Bode’s Galaxy

Nearly full moon and just a little data

[mint merlin]

ayeee

[burnt bay]

Some vague hints of dust lanes and spiral arms but it’s rough

[burnt bay]

Cigar Galaxy looking much better

[burnt bay]

Uhhh the Needle Galaxy

Couldn’t see it visually

Kinda close to the moon

[static turtle]

Wish i did

[spark sail]

How much long exposure images should i take with my dob for m13?
My dob is 1200mm f/5.9

[ornate spade]

find out your cameras pixel size and plug everything into this calculator(pinned message in this channel also) https://docs.google.com/spreadsheets/d/1tSEbji6V4rYz81COybiD5LWaekULIQReJy7kZCxQy78/edit?usp=drivesdk

[ornate spade]

I'm guessing it would be somewhere around 0.2-0.3 seconds. I haven't tried it yet but you could pretend your pixels are twice as big for that calculaton, then use pipp to bin four pixels into a big pixel. Could get more light at a lower resolution.

[spark sail]

Yeah i got 0.3 s

So after taking the lights , darks and bias should i stack them in siril?

[ornate spade]

I'd recommend deep sky stacker, you also probably want to do a bit shorter of an exposure time for a globular cluster, or the stars would look a bit ovalish.

[spark sail]

Ok then i will try 0.2s iso 800 and stack them in dss

Thanks

[dreamy dew]

From M78 to M42 in Orion (untracked) - collected lights from several winter nights from last year.
Kinda wished i had a full frame camera. though..was able to get the framing I had in my mind.. but too tight.

Equipment used:
Canon EOS 80D, Samyang 135mm F2.0 ED prime telephoto Lens, Digitek tripod

Data acquisition:
Lights: 5612 x 1 seconds, F2.0, ISO 3200; 20 dark frames with same settings as Lights; No bias and flat frames.
Total integration time of 1.5 hours approx.
Average bortle scale of the sky: 5

Processing:
Stacked in DSS (Rejection - Median Kappa Sigma Clipping)
DBE, ABE and Photometric Color calibration in Pixinsight
Stretching and Star reduction in SIRIL 1.2.0 beta
Denoised in Topaz Denoise
Final adjustments in Adobe Photoshop

[hallow tapir]

That’s extremely impressive for untracked

[dreamy dew]

thank you 🙂

[mint merlin]

@ornate pier nerd this guy?

[tidal tide]

one recommendation from me is to not use topaz for astro

[dusk mantle]

still looks noisey

[upper pasture]

Looks great for untracked, and a small amount of data (i consider 1.5 hours to be a pretty small amount, others might disagree). Of course the fast 135mm helps. Great job!

[gentle birch]

I can't stand outside in winter canada for more than an hour so props to you, wherever you may live!

[hallow cove]

is it noise or is it dust? (probably a mix of the both)

[dreamy dew]

yeah..i live in South India (tropic). not so cold out here even on winters.

[dreamy dew]

got it. i agree, sometimes it destroys the image and also the stars all the time

[mint merlin]

ton of noise

but theres also a ton of dust

[hallow tapir]

Hi

[hallow cove]

hello

[gleaming walrus]

Finally 🤣

[junior axle]

Hi, i have some questions to ask since i got my DSLR willing to do some nightscape photography. Is there any free option for MAC users to have a stacking tool like sequator that keeps terrain? i already have astap, Gimp and Siril intalled. Should i buy a 50mm 1.8 canon lenls for my canon eos 800D?

[gleaming walrus]

Siril will be good for stacking,
Yes 50mm is a good lens

I take most of my images with it

[ornate spade]

I have the canon 50mm F1.8 II lens, I had to mod it(remove the silver ring) to get it to focus with my 600D. It collects light really quickly, but the coma further from the center is ugly. Picture is around 40 minutes of the carina nebula area.

[junior axle]

thank you both for the info!! @gleaming walrus @ornate spade. Do you have an alternative to sequator to keep terrain for mac? or this can be done with Siril as well?

[ornate spade]

Here's a single 2s exposure, you can see the coma easily on the bright star to the left. This is a jpg through.

[ornate spade]

Don't people normally shoot both separately then combine them as layers in editing? No idea through.

[junior axle]

really dont know 😛

[gleaming walrus]

Yes, it has coma but we are doing untracked and we crop the sides anyway,

Even though it looks bad it is ok for what it can do,
I close the aperture to F2.5 or 2.8 all the time

Captured this with 750d and 50mm

I had some issues due to trailing stars a bit but it's an okish one

[dusty gull]

Yep but it's a lot easier to do this if the foreground is "sharp", when it's all over the place it's harder to manage or you loose some data

Also secator is fast and includes distorsion correction so it's nice to have it for widefield

[ornate spade]

Second attempt at the Large Magellanic Cloud, had some stray light issues and processing definitely needs to be improved but the Tarantula nebula turned out nice :3

Is there a good processing tutorial for Siril?

Canon 600D 50mm F1.8 II lens at F2. 37 minutes with 8s subs.

[void condor]

lmc?

[hallow tapir]

untracked mw this was gonna be a star trail Timelapse but managed to salvage quite a bit of data into a non trailed image

[glossy knoll]

I took advantage of my camera lens big FOV to catch 3 nebulas orion,horse head,M78

[sharp heath]

I guess I am leaving this forum

[ornate spade]

What is the deal with the banding near the bottom? Maybe try to restack in normal mode with orion centered in the reference frame to get better results in that region? You could also crop the underexposed areas near the bottom and the left to make it look a bit better. Impressed that you got that in bortle 9 through.

[ornate spade]

suffering from success

[sharp heath]

One of his frames was off the screen. Prob bc he forgot to recenter

[sharp heath]

It’s so much better

[glossy knoll]

I didn’t center it on orion nebula to catch a reflection nebula in the bottom but i can’t because it was very low but i didn’t know when i was catching photos

[sharp heath]

[hybrid basin]

I will come back

[cinder vault]

I'm a member of the #NeverBeenUntracked gang

[gentle birch]

[compact dust]

Taken with 50€ Gear in the light dome of Bratislava

[hybrid basin]

I'm partly untracked now 🥳

[dusty gull]

Welcome to hell!

[hybrid basin]

Why 😁

[dusty gull]

Untracked is a pain haha

But it is quite rewarding

[hybrid basin]

Ar least I can take 0,1s as fas as I know

[hybrid basin]

I know. I started untracked and built my tracker myself. Now I'm partly untracked again. At least I have a mirrorless cam

I want to try lucky imaging, if my scope is sharo enough.

[dusty gull]

What's your mirror size?

[hybrid basin]

10" should be enough, and its F4.8

[burnt bay]

Oh then you probably won’t have too rough of a time

What cam

[hybrid basin]

10"...

[hybrid basin]

Stock Nikon Z50

Relatively good in noise I heard

[burnt bay]

Nice

Probably a wide sensor I’d imagine, should make it a lot easier

[hybrid basin]

I also want to try planetary, because I also got a Barlow lens.

[hybrid basin]

Its APS-C...

[burnt bay]

Still quite a bit better than planetary cams, the imx462 is 5.6x3.2mm

idk if that’s the right thing or if I’m stupid

[hybrid basin]

Yes at least I have a lot zoom, so lucky imaging is more useful...

Now only my mirror has to be sharp. There is really much dust and many hairs on it. I have to clean it, but that for I'll go to a local astronomy club to ask if its really needed and how to do it...

[real furnace]

2 minutes in the Beehive Cluster tonight. Had some banding problems and couldn't stack all of the data because of the lack of memory in my laptop

[covert scarab]

is an 8" good enough?

[burnt bay]

Yep, I use a 6” and @dusty gull gets excellent stuff using a 5”

[covert scarab]

I'm looking into getting a Uranus C astro cam

[meager tinsel]

highly recommend

[dusty gull]

Yeah it's a really good value

[robust sonnet]

what focal length?

[sharp heath]

You need to stop down

luckily im not at the point of throwing up

i just feel really weak

and my throat hurts like crazyyyyyyyyyyyyyyyyyyyy

[gleaming flower]

drink some tea with honey, helps with the throat pain

[hallow cove]

drink like 2 litres of water

thats my dads strategy

[meager tinsel]

hey so are there any completely impossible targets to capture untracked with less than 1 second exposure times? im thinking in messier objects, just curious for my future endeavors

[grave rapids]

I think technically they’re all possible but most of them would not be worthwhile

[meager tinsel]

which ones wouldn’t be great ideas to capture?

this is with a 150p and uranus c btw

[grave rapids]

Oh that’s actually a very good untracked rig

[meager tinsel]

oh really that’s good

[grave rapids]

You’ll probably have decent luck with most of the galaxies and planetary nebula

[meager tinsel]

any ones to avoid?

[grave rapids]

None that come to mind

But you’ll struggle with bigger nebula like North American nebula or elephant trunk

[meager tinsel]

yea orion and andromeda don’t fit at all

[tidal tide]

pillars of creation might be an option

[ornate spade]

Tarantula nebula, 962 0.8s subs(~12.8 minutes integration time) with an 8" F6 dob and canon 600D.
Did additive 2x2 bin in pipp and it turned out much better than I expected, allowed me to take 0.8s subs instead of 0.4s at the cost of resolution. Will definetly try cheating by binning again.
Thought that dim object to the right was a galaxy but it's actually NGC 2108: a globular cluster 150k light years away.

[robust sonnet]

DANG U DID THIS UNTRACKED?!

[ornate spade]

Yep, was a pain as I literally could not see the nebula in liveview. Had to take 2.5" exposures to figure out the proper framing. Binning helped quite a lot, as it allowed me to take 0.8s subs instead of 0.4s. Only problem is that I used up another 1% of my shutters lifetime just for this picture.

[robust sonnet]

im getting an 8 inch dob soon (hopefully). I was planning on having it be just an awesome visual scope but ig i could use it for astrophotography if i wanted to

[ornate spade]

You do need to find the brightest targets to get much out of it(Orion nebula was quite a lot better even with 0.3s exposures unbinned, but still could only get the core), also I have a setup that takes a picture every ~2s which stops the shutter from vibrating the telescope in the next exposure.

[ornate spade]

This is sombrero galaxy (~1000 0.3s exposures unbinned) for an example of why you'd want to shoot the brightest objects. Planetary is really nice for an 8" through, but with a DSLR it's a pain, at least in my case where I have to record liveview 5x to get 1:1 sampling, oh and limited to 30fps video capture.

[burnt bay]

Get a planetary cam. They make untracked dso imaging much better

though the small sensors are a pain

[strange seal]

The 5x 1:1 crop is also compressed

[paper arrow]

i dont know how, inly just saw this channel

ill just show all my untracked photos ig\

lmk what yall think

been doing untracked for a year, i know what im doing

got that skillzzzz

Hey it would be? Good if yo crop it in the middle

[dry spade]

Yeah that looks pretty good IMO 🤷‍♂️

[static turtle]

Yeah with calibrations it would be very good

The edges are rough but for a first yeah!

[dry spade]

If he still has the originals, gradient removal on each frame before stacking might help

[static turtle]

Yeah

[neat scroll]

do you guys think drizzle should work when doing untracked?

[paper arrow]

i never use drizzle

mainly bc idk what it does

[strange seal]

Don’t bother.

[neat scroll]

why not?

[strange seal]

Data isn’t good enough to warrant the larger file sizes. Noise reduction might be more challenging. Not dithered properly.

https://www.cloudynights.com/topic/642593-eaa-with-a-manual-dobson-it´s-working/

not exactly astrophotagrphy as its eaa but i thought it was an intersting way for untracked imaging

[real furnace]

I believe this was around 10 minutes of exposure time in a bortle 7

[paper arrow]

Not bad

Get more

This is 1 hour 10mins

[paper arrow]

Has anyone done helix nebula untracked ?

[real furnace]

Now that I have a tracker, I’ll certainly get more. The problem is that Rho doesn’t get that high here

[gentle cipher]

Woahhh what gear was that with?

Was a pain to get the data too, as I had to reframe every three minutes without being able to see the stars on the liveview screen. It is a shame how slow it is for me to get data, as I only got ~5 minutes worth within 45 minutes....

[sterile violet]

[paper arrow]

I've seen a few people framing the lagoon like this which I really liked

So I gave it a run

Oh yeah in general, I like close-ups of MW that have Lagoon in them

Barely any integration

Yet there's so much there

Oh yea

The mw is really bright

Was gonna shoot some MW then something in the bush was moving around a lot

And I couldn't see it

So I went back inside

[sterile violet]

Awww lol

Fair enough

[paper arrow]

Bro the other day there was something moving in the bushes and it was a huge ass possum

[sterile violet]

Hey since you're in Aus, are you able to shoot a very wide-field MW untracked?

[paper arrow]

The size of a pc keyboard

[sterile violet]

[sterile violet]

💀 that's big

[paper arrow]

I haven't done a mosaic since I don't have pixinsight

[sterile violet]

Ooh I see

[paper arrow]

I was thinking about doing one but framing it up perfectly is extremely ass then bx you'll need to be precise

There probs are other ways

But most use pix

[sterile violet]

I was at f/4, you would've been 5.6

[hexed pelican]

Ah yeah

Are those 55-250mm lens good? I've been looking at picking one up but I haven't been sure if I should

[paper arrow]

Someone I know said they got triangle stars at 250

Yeah that looks quite good to me

The 75-300 has issues from what I've seen

That's got quality control issues

But if you are ge5tint a new lens, I reccomend rokinon 135

[hexed pelican]

I'll have a look into it

[paper arrow]

It's more expensive

But it's really good

[hexed pelican]

Yeah probably has much better quality control too

[paper arrow]

They do have some quality issues

But they will give take an exchange or replacement

[hexed pelican]

That's good, do you know how obtainable they are in New Zealand? It can be hard to get stuff here

[paper arrow]

Amazon

Or from the rokiinon website

[hexed pelican]

Sick

Thanks

[paper arrow]

All good

[gentle birch]

I’m a chef the way I be cooking these images

[paper arrow]

Carina has really good oiii which can be a struggle to really pull out

Still my favourite nebula I've done

[neat scroll]

yeah it's super bright

hopefully i'll get better results tracked but the mount broke

[paper arrow]

Ah

[neat scroll]

lmao

[mossy cave]

Canon M5 modded @ ISO3200, Canon 50mm f1.8 STM @ f4. 727x2.5s subs. Bortle4/5 no astrodark

was doing the basic wire shutter pressed down and cam on continous mode

i missed abit. didnt plan on imaging but aimed "around there is nice" and started shooting

[sterile violet]

Dumbbell is cool but what happened here

Why are the stars like circling around the nebula

[finite spire]

Uhh the camera probably moved when recording

[sterile violet]

[burnt bay]

field rotation

[sterile violet]

slightly better process, better stars and nebule

bortle 7, 1 hour

[paper arrow]

I wanna do this

Just need the timing

And new moon phase

[sterile violet]

9 mins of data

should be a fun process

[paper arrow]

@sterile violet what did you use to stack?

[sterile violet]

deep sky stacker

[paper arrow]

Huh...alright

[tidal tide]

pretty damn nice, might want to crop the bottom a bit

[hallow tapir]

30 minutes untracked

[paper arrow]

pretty decent

your stars arent

[hallow tapir]

Captured in bortle 2 skies

[paper arrow]

you should do the MPF rule so you can calculate your exposure time before your stars trail

yea was wondering how you were able to get the backpoint so low

ive sent my proccess in the #1021002743080558642

[warped ledge]

i had like 6 min on this image

The clear advantige of a filter

[mental sky]

I personally think you should stop down a bit, as much as it makes it easier, especially untracked, you can see the star shapes are being weird around the edges

[warped ledge]

Yeah, because if the lens

[mental sky]

if you stop down a tiny bit, it will take slightly more time to achieve the same result, but the stars will have much less of a triangular shape

[warped ledge]

Ohh

[mental sky]

Yeah, I think it’ll be worth it next time

[sterile violet]

Yeah I should

[earnest quarry]

5sec sub

Mosaic of moon prime focus using webcam and 114/900 scope 7 panels

first time doing deep space astrophotography since april

40 minutes integration

[inner crystal]

Looks great. Really like the processing!
What was your setup?

[gentle birch]

nikon d750 with a f5.6 300mm lens

[gentle birch]

thank you!

[paper arrow]

That's pretty solid

[marble kite]

@gentle birch I'm thinking ab switching to the d750 but how is it for ap and just day time in general?

[gentle birch]

it's a great camera, just wish it had a touchscreen

and it doesn't have a 360 degree swivelling display

[marble kite]

Alr great. Yes I don't mind that it doesnt have touchscreen but I can't really decide between the d750 and d4

But I think im going for the d750 becouse of the price

[strange seal]

750 is a super nice camera

used it myself for a couple years

[urban dirge]

untracked moon crater

[marble kite]

alr cool

imma go for the 750 then

[paper arrow]

another edit

did a MW mosaic untracked

[gentle cipher]

my condolences

untracked mosaics..............

[paper arrow]

yea they are a pain to process

so much noise

but pretty cool

it stretches from altair towards crux

nearely cygnus

also did this

and this one is quite noisy

i should call myself the untracked king here

can i have a special role for being untracked

[real furnace]

tohu:

[meager tinsel]

poivre:

[paper arrow]

Me

[tidal tide]

nah lmao

[hallow tapir]

They are so ol

Cool

I take a few

[gentle birch]

yo i get pretty good SNR for untracked standards too

[gleaming walrus]

Milkyway panaroma with zodiacal light

Took this in feb

[gentle birch]

bro i swear dinesh is just cracked at astrophotography in general

[gleaming walrus]

Haha no, just learning,

Took some timelapses from B1 this june hoping it will come out great but gonna take some months

[real furnace]

Your southern sky image is insane

[gleaming walrus]

Carina and Coalsack?

[real furnace]

this

[gleaming walrus]

Yes, that is my best untracked image so far

[maiden drum]

bruh

my camera literally shook between shutter clicks

[sterile violet]

the shutter shook it?

[paper arrow]

Might need a mirror lock delay

[paper arrow]

Not bad

[finite spire]

Bru

That’s the only thing only untracked can do

[paper arrow]

you can do nebulas as well

just needs a bit more skill

[finite spire]

It’s easy trust

[maiden drum]

what object is the left bottom

[maiden drum]

i tried dumbell yesterday but my sub (0.8s, 200mm, eos 750d) came out very faint

[paper arrow]

Messier 1

[gentle birch]

have you seen any of my pictures💀

[finite spire]

I mean exclusively

[warped ledge]

Smc?

[paper arrow]

yes

[warped ledge]

Nice

[cerulean nymph]

I'm so out of practise. Just noticed I had the ISO on 3200 and not 1600 and the stars are bloated and over-exposed and the noise is awful. Nonetheless - it's an image of comet nishimura.

[urban dirge]

@gentle birch first try on andromeda and used your advice i dont have a remote shutter button so not that good its 40 light frames and 20 flats

[gentle birch]

you'll want much more lights than that. Get at least 500

otherwise this looks promising. What was your focal length?

[urban dirge]

250mm

i have 300

[gentle birch]

then maybe your focus is a bit off

[urban dirge]

yea

[gentle birch]

do you have a bahtinov mask

[urban dirge]

nope ill get one tho

ill try again today its good wheather

do you have any advice

[gentle birch]

refocus every once in a while

even though you nail it before you start imaging the focus will shift with time

[urban dirge]

okay thanks!

[urban dirge]

should i use tape to keep the focus?

[gentle birch]

personally i don't

[urban dirge]

do you have a bahtinov mask if you do what do you have
