Here is my first pass at processing some data:
AT 115 w/ fffr
ASI 1600 cooled
ZWO FIlter wheel
ZWO ASI 120 (??) guide camera and OAG
20x120" each of Ha, OIII, SII, and Lum.
A lot of Bias
0 flats (Accidentally deleted the folder...oops)
Note - I'll post the exact specs if I clean it up.
A few notes:
1. The stars on the edges clearly have an abnormal shape. The eccentricity increases and they are a bit lopsided. I think this indicates that the spacing to my new camera, an ASI 1600 was a bit off.
2. It's overly red for my taste, but it's a start.
Any CC is welcome, especially about the star shape.
Wow, that's impressive - even if the star shapes at the edges are not ideal. The detail in the middle and the overall amount of nebulosity is abundant. This makes me wish I had a real astro camera and narrowband filters! Are your skies fairly dark or are you dealing with light pollution?
Yes, I wonder if those oblong stars is due to the focal field not being flat enough, because of the spacing to the sensor as you mention.
