Hello everyone!
I would like your advice regarding a few issues I'm having with an image I took a few days ago. This is my first DSO image and while I'm happy with it, I'm sure there are a lot of things that can be improved.
The issues my inexperienced eyes can detect are:
The stars away from the center of the image are elongated, but they are not all pointing away or towards the center (which I understand would imply a wrong flattener – camera distance). This can be seen in the 2 light frames shared.
The vast majority of the stars are yellow. Could this be a processing issue? (I know there are a lot more yellow/white stars than blue, but still…). I was imaging at about 46 deg N and the target was between 60 and 80 deg Alt so I don't think the atmosphere was the reason.
You can find a light frame from each session, unprocessed stack and the final effort (jpg) here:

If needed, you can find the details regarding equipment/technique as an attachment so that I can keep the length of this post reasonable.
If there’s anything else that I forgot to add, please let me know.
Any feedback from you is greatly appreciated!
Thank you!
Cheers,
Mihai
