Hi George,
If your going to give CCD stack a go i would recommend watching Ken Crawford's Video's
https://www.youtube.com/watch?v=zSgO8kIWI5s
My attempts at using CCD stack before watching his video's were Futile.
I have never used Pixinsight everyone i talk to about it say its very complicated.I would not pay a small fortune for a program i would never get my head around
. Its above my abilities.
Your 2 images seem to have lots of noise and some odd Vertical banding thing going on.
Seems odd given that your using an Atik 383 the same camera that i use except i use the mono version. Your other images i have seen don't seem to suffer from it. Maybe you just need more data
.
What Temp did you run your chip at?
