Workflow for multi-color mono subs correct with Mabula’s remarks:
1) Create master BIAS (app. 100 -250 subs), clear all frames
2) Create master DARK (app. 50 subs), clear all frames
3) Create master FLAT (app. 50 subs) while loading master BIAS, clear all frames
4) Create Bad Pixel Map while loading master DARK and master FLAT, clear all frames
5) Calibrate subs while loading Bad Pixel Map, master DARK and master FLAT
6a) For additional colour subs only: Load reference frame and perform star analyses on all frames and unselect reference frame and select it under Registration as reference frame
6b) For first colour subs only: perform Star Analyses and remember selected reference frame
7) Select Windsor Clipping in Integrate and press Stack to Register, Normalise and Integrate frames of this colour
8) Repeat step 3, 4, 5, 6 and 7 for each color filter applied
9) When needed correct light pollution, vignetting (when no FLAT’s were used) and combine colours to a single RGB stack
10) Optimise photo using preferred tooling…
