The photo below is of the Trifid Nebula, M20, located in Sagittarius. It was capture in August of
2006 with the SXV-H9, through Astronomik LRGB filters in a TrueTech color wheel mounted on
an ED100, with Lumicon focal reducer, at f/6. The exposure info is Lum: 35 X 2 1/2min; R & G: 35 X
1min; B: 32 X 1 1/4min.
Processing relied on a light DDP application in Maxim followed by a log stretch using Liberator
in PS CS2 (to maintain more natural looking stars, pure DDP is too harsh due to "ringing" on star
edges).
The Maxim multipoint flattener was used on individual (LRGB) layers, but the background was
still insufficiently flat, so a pass through GradientXterminator was also made in PS (the original
had a very complex, multicolored background due to several different lights in the local area,
and no bandcut pollution filter being used).
