Hi. I'm trying to wrap my head around our larger scope as we finally have some images to process. The camera is an FLI ML16200.
The following is a stack of Ha, 110 6- minute subs which have been calibrated, aligned and integrated:
Here is the same image with a very quick ABE, which makes it much easier to see the background pattern:
Note tha pattern in the background. From noise? Chip pattern? Light pollution/sky noise?
Here is a stack from the same Ha images, calibrated but NOT aligned. I did this to see if I saw any type of chip pattern, but I don't really:
Any thoughts as to the source of this pattern? Thoughts on how to eliminate it during capture or processing? Note the subs are not dithered.
Thanks. Andy
