Calibration frames have made a big difference to my images as I have inherent vignetting due to my incredible TS GPU coma corrector that provides pinpoint stars to edge of frame.
Calibration is not a chore and doesn’t add to much time to my process, it’s part of the overall AP experience.
I use the whole calibration suite with my 2600MC and 2600MM ….,
I create a new Dark Library every 9 to 12 months in my study ( takes a day ) which cover all my exposure lengths , 2 Gain settings ( 0 and 100 ) all at -10C .
I do my Flats and Flat Darks either after a capture session or the next night if it’s cloudy ( we rarely get successive clear nights in Sydney )
Flats for one filter takes 5mins , Flat Darks take 5 mins
Im a bit OC as I take Flats and Flat Darks for each project.
Imaging under crappy heavy light polluted B8 skies in Sydney , Calibration and Dithering are a must to give my stacking in ASTAP and processing in Startools every chance of a half decent high signal , low noise , higher fidelity image that I can be proud of.
Cheers
