The Witch's Broom Nebula
Part of the much larger Cygnus Loop, it's the ionised gas remnants of a supernova and is around 1470 LYs from Earth. The area is VAST ( it would take me a month of solid imaging to capture it all on this camera and scope set up).
This image is a mono capture using two filters to capture light from different gases in the nebula: Hydrogen alpha and Oxygen 3. These have then been combined into Red = Ha, Blue and Green = O3.
I love shooting this area of the sky as the detail that comes out is fantastic - shame it's only visible in the summer when dark hours are down to a couple per night.
QHY163m, Skywatcher 130pds (with 0.9x coma corrector)
Baader 7nm Ha and 8nm O3 filters
Stacked in AstroPixelProcessor and processed in PixInsight
50x240s exposures per filter, 20 darks, 20 flats, 20 dark flats
