Description

Decided to make the jump to a cooled, dedicated OSC astronomy camera. It does a much better job of capturing detail with less noise than the mirrorless camera. Thrilled with the improvement over my last image.

Description: Since it's been snowy, I went ahead and applied a new processing technique to this data. Originally, I stacked in DSS and then did just about everything else in photoshop with a little Starnet action in between. This, I think, led to some rather haphazard guesses about white points, black points, and color balance/saturation.

I am now primarily processing in Siril: start with the OSC Preprocessing Script, Photometric Color Calibration, Green Noise Removal, Background Extraction, and Starnet Star Removal (with pre-stretch and no drizzle). Then a gentle Asinh Transformation, a few rounds of Histogram stretching, and some Color Saturation (global and specific), before exporting a tif into PS for some NoiseXterminator, and more fine tuned saturation, sharpening, noise reduction, and color work with the Camera Raw tool. Then that tif comes back into Siril and is saved as a fit for star recombination. This process gives me much better control over the image colors, saturation, and balance, and better control over star size than my old method, and I'm much more pleased with the result!
