Hi All- Don't know if anyone else had a chance to image last night, but will throw in my efforts... Haven't had a chance to work on flat fielding, but here is a 2 minute exposure of comet plus M33 with the C-14 + Hyperstar + Canon 20Da (660mm @ F/1.9): http://alice.as.arizona.edu/~ketelsen/Tutle_M33_30DecSM.jpg Also, with all these bright things in the sky, here is a shot with a 35mm lens @ F/4 for 3 minutes (had to work to fit them all in, north is towards the lower right). You got your Tuttle plus M-33, Andromeda Galaxy, Comet Holmes plus the Double Cluster taking up the 4 corners of the shot: http://alice.as.arizona.edu/~ketelsen/Tuttle_et_al.jpg -Dean -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
