Description

SharpCap Pro live stacking with master dark. No post processing.

Compare to previous image here that has a greenish cast (same setup used):



I figured out how to get better color balance: While on my target, adjust the R and B sliders using the smart histogram before taking the master dark. Then take the master dark using the same color balance. Previously I just set the R and B sliders at 50 for the master dark, but this resulted in images with a greenish cast. If I use the same color balance for the master dark as I do for the light frames, the greenish cast is not present during live stacking.
