Galaxy M33 in Triangulum

An old favourite I've imaged several times.

7 x 5-minute exposures at ISO 1600, f/4. Manually guided off-axis. 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.
