2023-11-15 Scope : CFF 135/926 Mount : EQ6R-Pro (DFO StellarDrive) Camera : QHY600 Lite Filters : Chroma • Red : 80 x 240s • Green: 80 x 240s • Blue : 89 x 240s Total Integration : 16.6 hours This is a rather faint target and not easy from our Bortle 4 skies. I spent hours trying to remove light pollution gradients before finding an acceptable, if not ideal solution. Noise was also problematic and again I settled for a compromise solution which has removed the worst noise but has made the image look slightly waxy. Data for this image was captured over five sessions between August and November 2023.
