Rosette Nebula, NGC 2237-9 and cluster NGC 2244 in Monoceros
I last imaged this with the same setup a year ago, but here I managed to get more sub-exposures. Last time, the clouds moved in after just 3 frames; this time dew on the lens limited me to 8.
8 x 7-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.
