Globular Cluster M13 in Hercules
Not the first image I've posted on Flickr of this subject, but the first time I've imaged it with the 12" 'scope.

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; final noise reduction using CyberLink PhotoDirector.
