Captured with my Celestron CPC 800 Edge HD (C8 Edge HD on fork mount and wedge) with a reducer and a ZWO ASI 290MM with 0,5 second exposures and 460 Gain from a small city in germany.
13500 pictures as Red were used as luminance, but also 2700 of these Red pictures were used for RGB, same as blue and green.
Stacked in SiriL, stretched with StarTools and color calibrated, background and stars are not processed in any way, only stretched. Only the nebula itself is sharpened a bit in Fitswork.
