I moved the QHY168C camera to the Celestron C14 last night & took 260 1 minute subs through the Baader IR/UVcut filter at F7.7
The integrated sub looked very strange with a very odd colour cast which I was not too concerned with- colour casts are not abnormal. When I tried to clean up the image it was covered in green noise.
When I split the raw sub I saw that the blue channel was exceptionally noisy & broken, very weak & pushed to the far right of the red & green channels. See the histogram from the unprocessed sub.
Please see the attached screen shot. Could I suspect that the blue channel has developed a fault?- since this is the first image through the new setup I have nothing to compare but its very odd that the L, Red & Green channels look okay.
I would be grateful for your thoughts.
