One of my all-time favorite objects, this enormous hydrogen bubble in Cepheus.
All imaging was done from the observatory in Meldert, using the GM2000, Esprit 120 F7 and the ASI2600MM. This current draft is an LRGB combination with about 6 hrs 45m of lights (each 30″)
I hope to add an H-Alph 3,5 nm layer in next the clear nights, and then maybe get some help in decent processing (this is a quick processing straight out of astropixelprocessor with some obvious faults – RED stars a.o. – in the image)…

Update on September 27th
Two clear nights under a nearly full Moon, allowed me to add about 90 frames of Hydrogen-Alpha, 3,5nm Baader filter. Each frame 10 minutes, or resulting in 900 minutes of exposure time = 15 hours.
My local PC configuration doesn’t allow me anymore to use for instance Pixelprocessor to combine all channels. It simply pops out during integration of these hundreds of frames. I guess it’s time to call in the help from Jean – our club processing specialist.
This is the stretched resulting H-Alpha stack:
