Description

I've processed this set of subs several times. Separately in APP and PI. The problem I have with this image is noise. I didn't dither during capture and if I recall correctly, the object was low on the horizon. Total integration time is 100 minutes. I would have expected a bit less noise. In the end the final processing that produced a result I thought it is half decent was integration using APP, then removing light pollution with the APP tool. I used PI  photometric color calibration and cropped the image in PI too. Just very minor curves tweaking in PS. No denoise. I tried Topaz and TGVDenoise, and they both made the image worse. I'll try again later this year.
