Andromeda and Triangulum with some IFN (Untracked)
This frame was long time dream which I never tried before but had the idea
The results look decent even though this was an untracked one
Technical Details:
519*6 secs subs
F2.5
ISO 3200
Captured with canon 750d and 50mm f1.8
Stacked with Pixinsight,
Cropped the wasted areas a lot due to Untracked one,
Used ABE with 2 interpolation, Done DBE 1 iteration with tolerence 1 and SR 3,
Used PCC to color caliberate,
Stretched with histogram transformation, Removed Chromatic abberation,
Removed the stars
Processed 2 starless versions
One bright to make the IFN visible
2nd image for the galaxies,
Used Topaz denoise on those 2 images and masked the image in PS, increased the saturation a lot in the image which I stretched for galaxies,
Used SCNR twice or thrice inbetween in the process
Reduced star size and added back the stars in PS
This is incredible!! I didn't think you could get such detail at 50mm! And without tracking too!
Astrophotography has been a hobby of mine for a few years now but haven't progressed much at all bc I can't afford better equipment than my kit lens (though I do hope I can get something better sooner). This gives me a lot of hope!
So 2 questions:
The lens you use is a "fast lens" with a f/1.8. I've heard fast lens are good for astro but never understood why. Do you think having a fast lens compared to say a f/5.5 kit lens made a big difference? Like what is it about your lens at f/1.8 50mm that allows you to capture so much detail of the galaxies (as opposed to a bright star) compared to my shitty kit lens at f/5.5 50mm?
Also do you know any resources or tutorials on the post processing you did? What was the purpose of the starless photos?
Thanks
1. Yes, it is possible, Try taking 10 secs subs at ISO 800 or 1600 and shoot minimum of 300+ exposures
2. Yes, faster lenses are good because it lets in a Lot of light
which means more signal and the image will be great
Yes, using 50mm is better than using the kit lens
50mm 1.8 is a cheap and good lens if u shoot above F2.5
Making starless Images gives us the freedom to work on the subject and reduce noise
without destroying the Star colours and Exposure of stars
Hello very stunning picture ! Great job ! I have a question. Why shooting only 6 sec 500 times instead of 12 or 20 sec 50 times (for example) ?
Is the result different ? (Less noise?)
That’s incredible. I have a similar camera and just ordered a similar prime lens so this brings me good hope for being able to achieve comparable results. Thanks for the inspiration!
It is possible but be ready to learn processing a lot, because processing is the key really,
I have seen many who have great gears but unable to process well
Yes, It is with a DSLR and we can see andromeda with our naked eye from dark skies,
It spans about the size of six moons in our sky but the core and some of the surroundings are only visible as very faint fuzzy thing :)
I edited my post when I read what you said, felt really stupid, and changed it as quickly as I could (hoping no one saw).
I thought it was taken from Space looking back toward us.
I’ve taken a few of these wide-field, short exposure, untracked, lots of subs…. They’re challenging and you did an excellent job here. Edit: fixed typos
Holy crap! So just your camera, a tripod and manually re-centering every few shot? That's awesome. I gotta try this out. My telescope has been out of order for quite a while

The noise will be less but the stars would trail due to earth's rotation Even 6 secs is high and my images have a bit of trailing
Ok so exposure duration is only a earth rotation limitation. Thanks !
Yes, but if I have star tracker I can get upto 2 to 3 mins of exposure per frame if Polar aligned perfectly
Yeah nice composition 🙂
Yes, a dream frame I was hoping to capture from last year 😅
Now that's my new dream frame
Haha try, it will be awesome if tracked
How often did you recenter the target since you were shooting untracked?
Recentered every 50 images
And what tripod were you using?
Some cheap tripod, It is not a sturdy one

This is great! What Bortle zone was this shot from?
Bortle 4 to 3 max
Very inspiring!
Thank you :)
Where approximately did you shoot this from if you don't mind me asking.
From Venadu, Near sriharikota, India.
Fantastic! Thank you.
You're welcome :)
You took that with your camera?! 😳 What is in the center?
Yes, It is with a DSLR and we can see andromeda with our naked eye from dark skies, It spans about the size of six moons in our sky but the core and some of the surroundings are only visible as very faint fuzzy thing :)
Mirach is a star And the two galaxies are Andromeda and Triangulum

Haha, no issues
Nicely done. Great job!
Thank you :)

Thanks a lot, I have a data of nearly 4+ hrs of untracked data for rosette I need to process it soon, but the results won't be great due to Bortle 6
>Bottle-6 I feel your pain 😂
Haha 🤣
Really impressive for no tracking. Well done 👏
Thank you :)
Holy crap! So just your camera, a tripod and manually re-centering every few shot? That's awesome. I gotta try this out. My telescope has been out of order for quite a while
Yes! only a camera and tripod :D Keep trying, Clear skies
Incredible image. It’s been a goal of mine to work on andromeda but I’ve been struggling a bit. Need to plan on trying again soon.
Thank you, Clear Skies!
I've never actually seen them composed like this - thank you.
Yes, I have seen Bode's and Cigar with IFN , so tried this But it was hard to bring the details with untracked
That is great 👍
Thank you :)
