'Helix' Nebula, NGC 7293, in Aquarius
Not the first time I've imaged this, but it's a tricky subject from the UK - as it's rather far South, so remains close to the horizon.
Manually, off-axis guided for 13 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.
