Well I got a QHY10 the other day from the classifieds forum. So far I'm quite happy with it. A single 2min frame of Eta Carina exceeded what I was getting even with several hours from a previous attempt. Anyway some great pictures are attached, great in the quality of the camera only, the telescope setup attempt was crap as you can see by the wonderful focus and the mirrorflop that wasn't corrected.
Anyway question. The pictures had 10 bias and 20 dark frames taken with the same offset and gain settings as the light frames, all stacked in DSS. When I open the images in PixInsight and do a basic stretch they come out VERY green.
So the questions I have is, where does the green come from and what's the best way to get rid of it?
The attached pictures were fixed using dynamic background extraction followed by SCNR to eliminate the residual green. Somehow I think the picture shouldn't have been green to begin with.
Any tips?
