Description

Tried everything to produce an acceptable result for Saturn, but Blue channel was simply too noisy due to seeing, w/o ADC and at 20 degree over the horizon, with local seeing being worse than the 1.5" predicted by meteoblue. Finally combining 4 SER files (mixed exposure times 13ms-20ms, mixed Gain 200-300, within 12 minutes range) to extract 10.000 frames to stack (PIPP, Autostakkert, Registax, Fitswork). Taking the Red channel as luminance, used FitsWork to artificially construct the LRGB Learned a lot about what are the limitations ...
