Final Image of M51. 169 Frames with 30s exposure, makes a total of 84.5min exposure time. Gain 100 Postprosessing Workflow in Siril: - Removal of satellite Frames - Calibration with Darks and Flats - Registering - Removal of worst FWHM Frames - total of 169 frames out of 188 Frames to be processed - Debayering - Stacking - Photometric Color Correction - Background Extraction - Stretching using ASinH Algorithm - Slight Saturation enhancement

It seems the calibration with the flats didn't work that well. Tinted at the left and the right border (red and blue). Workflow: - Removal of worst satellite Frames - Calibration with Flats - Registering - total of 221 frames to be processed - Stacking - Cropping, Background extraction and denoising in GraXpert - Aberration Removal (Siril Script) - Photometric Color Correction - Stretching using ASinH Algorithm - Slight S-Curve adjustments - Slight Saturation adjustment
start
M101, stacked with Siril, autostreched, no further processing 345 Light Frames with 30s Exposure => 2h 52,5min total Exposure
start after pcc
M101 - stacked and autostreched after pcc (photometric color correction) 345 Light Frames with 30s Exposure => 2h 52,5min total Exposure
