Hi,
I am postprocessing all sub frames with pixinsight. I noticed that the masterdark is in landscape mode 1920x1080 whereas the subframe are in portrait mode 1080x1920. I have to rotate the masterdark to use it with pixinsight. Which direction should I rotate it 90° to keep the exact orientation with subframe? clockwise of counter clockwise?
In other works I want pixel (0,0) of the subframes to correspond to same pixel of the masterdark rotated 90° that could be either (0,1080) counter clockwise or (1920,0) clockwise. I hope my drawing is self explanatory.
Thanks for your answer.
Frederic
