The Double Cluster in Perseus
Comprising NGC 869 (lower left) and NGC 884 (upper right). Photographed in poor conditions: although I took around 30 frames, I deleted all but 5 that were less affected by wind and passing cloud. There's still some mistyness here around the brighter stars due to thin cloud.
Just 5 x 2.5-minute exposures at ISO 1600, f/6.25. Modified EOS 600D & Sky-Watcher ED80 refractor, piggybacked on a Celestron C8 telescope for manual guiding.
Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves and colour balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.
