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! *does the forum prefer "color" or "colour"?
