Globular Cluster M22 in Sagittarius
Modified EOS 600D,Revelation 12
This object is far to the south, and I only have a short time to image it between obstructions, hence the short exposures and high ISO. 13 x 1-minute exposures at ISO 3200, f/4.
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.
