EquipmentCelestron 9.25 working at F/6.3 , SBIG ST2000XM camera, IDAS LPS2 filter, Custom Scientific LRGB filters. 29 x 10 minutes luminance at 1x1 bin, 12:6:12 x 10 min RGB at 2x2 bin.
DescriptionFor long I was afraid of Messier 64 with its strong "eye" and its misty arms. In my light-polluted skies (red zone) I am fighting against heavy light pollution.
4h50 luminance under steady skies (20 May) and 5 h RGB (23 May) allowed me to get interesting detail down to the core of the "Black Eye" galaxy. I also worked on the misty arms to reveal their spiral shape, which is often half lost in the processing.
The colors of this galaxy are rather subtle and demanded a very light hand to be revealed without exaggeration.
