This was taken with a 16 year old Canon 60d unmodified primed focused on a 8 inch newtonian, guided on a 11 year old AVX mount with orion starshoot autoguider.
Images stacked with deep sky stacker, processing done with pixlinsight, process flow was crop, background extraction, color calibration, blur exterminator, noise exterminator, histogram stretch, then photoshop adjustments for colors.
What are these lines!? after Id lowered the ISO to 500 now I have these horizontal lines I never had them when I imaged with iso -1250 the light frames are 4 minutes long and these lines are still there with dark frams I haven’t tried flats yet I need to make a light box or something? any advice would be good

It looks like a banding issue; have you dithered it? It should be easily removed if you move the frame enough to avoid the overlap.
