hello, I recently stacked images that I took of andromeda with my iphone, but for some reason they are coming out weird, does anyone have any tips on how to process?
siril andromeda processing taken with iphone
i posted the images on my astrobin
I don't mean to be snarky but my best advice is to stop using a phone as an astrophoto camera. Yes you can sort of do it and if it's the only way forward for you then yes, do what you can. Just know that it's the wrong tool for the job in many ways. You've done some nightscapes of the Milkyway, something that is much better suited for a phone camera. I would stick to that as a gateway into astrophotography.

Honestly, I love your sky/landscape photos but your best deep sky images where done with a DSLR, not the phone.
Can you share the images so that we can see what aspects concern you?

We need more info to help you.
You did not mention or provide a link to your pictures.
I can see the following ones on your profiles, but you posted them after creating this thread:
Are these the pictures you are referring to?
If so, it would be interesting to know which settings you used on your phone, how many frames you shot, if you took calibration frames, etc.
It could also be helpful to provide example sub-frames.

yes sorry those are the images, I took them using nightcap with iso 2500 and exp1/1 and a focus of 98 with 30 second exposure, I took 55 light frames, 12 dark frames, 15 flat frames, and 32 bias frames ( this is my 1st time taking calibration frames so I might have done them a little wrong), unfortunately my computer is bein weird today so I can upload the sub frames.

Then by all means do what you can...

Besides focus issues, your images show elongated stars. Either correct your alignment and/or guiding or take shorter sub-frames.
Having less light/data is better than having blurry data. You can compensate by taking more sub-frame, if possible.
Also, try to take more calibration frames, especially darks. 12 is very low.
I'm not sure it's worth trying to fix these images. You'll make better use of your time trying again, in my humble opinion.
But that's up to you.
Good luck!
