Hi all,
I'm getting back into imaging after a long time away and am trying to relearn what I thought I knew.
I am disappointed in the RGB image below for various reasons. In particular, the diffraction patterns of the brightest stars are multicolored* - looks awful. I don't recall seeing this before or in other peoples' images.
Has anybody seen this kind of thing before? Is it something obvious? Is there a wavelength dependence of spike to center intensity? Maybe I did something wrong in post processing. I can of course provide the raw data if you think they will help.
Scope: 8" Newtonian
Camera: ZWO ASI1600
Subs 30 s each, 2 hours each channel. I think the Bortle is 5 or 6.
Please let me know what you think and if I can provide any more details. Thanks!
