Continuing my exporation of the Atik 460 OSC, I connected a Canon 200mm f/2.8L lens ( I guess in telescope terms it would be a 72mm f/2.8 refractor!) to it last night, and had a go at shooting M31, M33 and M45 before the lens began to dew up and the clouds rolled in.
First off is M31, which is a stack of 23 x 3min exposures:
Next up was M33 in Triangulum, this time comprised of 25 x 3min subframes:
And finally the Pleiades, M45. This was put together from just 8 x 3min exposures, and condensation was beginning to build up on the lens, I think, which cused the stars to look a little fatter than usual:
