Trifid Nebula, M20, in Sagittarius
Not sure this is my best image of this subject, but I was amazed to get this result from just 3 x 3-minute light frames! I couldn't get any more, as the Earth rotated the nebula behind an obstruction.
Some star-bloating towards the right again, but not as bad as the Veil image.
Manually, off-axis guided for 3 x 3-minute exposures at ISO 1600, f/4. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.
Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves & colour-balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.
