Just getting ready to try my new ASI533 MC Pro on C9.25/Hyperstar/Celestron Alu Dew shield. Took 20 x auto flats with ASI Air+ with led panel & 5 sheets of white paper. Histogram bump right in the middle but Master Flat looks odd - could it be the red USB3 & power cords affecting things? Doesn’t show too well in attached thumbnail but red tinge is bottom left. I taped both cords together quite tightly.
I have an Optolong light pollution filter on the cam
