OK - After some help from Peter Shah, here is an updated and less lurid version of this image.... Thanks Pete! M20 is a star-forming nebula located 9,000 light-years away from Earth in the constellation Sagittarius. Also known as the Trifid Nebula, M20 has an apparent magnitude of 6.3 and can be spotted with a small telescope - but better still - a whopping big one! Pier 8 consist of: Planewave CDK 17” f/6.8 Dall Kirkham, with a FLI Kepler 4040 CMOS camera After subframselection, I used 41 x L @ 60s, 26 x B @ 120s, 22 x G @ 120s and 38 x R @ 120s.
