The Sunflower Galaxy, M63 in Canes Venatici

Manually, off-axis guided for 12 x 4-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.

(I need to add the usual caveat that this fast telescope doesn't give nice round star images towards the edges due to coma).
