M83 (Southern Pinwheel)
Taken from Wiruna on Tuesday with f/7 110 mm refractor, 4 x 5 min each RGB, 8 x 5min L for a total of 100min. Camera is QSI 540. More data would be nice and I was going to collect some more yesterday, but sky murked over with thin cloud about 1am. Had some trouble finding a guide star with the OAG, so had to crop to centre target. Field is about 25' x 25'
