I believe that the Wgreen value in FC 2.7b modifies the green channel so that the blue level could be higher by comparison.
Since I don't have a QHY camera, I don't know how FC balances the colours using the W values - I had seen in another post on CN there the "default" values for the QHY cameras was 64,64,64 which I assumed was the halfway point for 0-127. I reckon the ratios from above are correct (or at least close), but I don't know what actual values you need - might be a case of trial and error? |
It's okay, based on the manual I should be running blue at 255 and scale everything down from there... if and when the skies clear up and this stupid SDK bug is fixed. I see no sign of hidden clipping occurring with green when experimenting at home with daylight objects which is reassuring!
