M31 Andromeda Galaxy
First light with new (to me) GSO 6" Ritchey Chretien
Nikon D5100
10x 180s subs
ZEQ25GT
Guided w/ 9x50 finderscope/Logitech Quickcam Pro 4000
Stacked using DeepSkyStacker, processed in StarTools.
This one was only minimally cropped to eliminate the stacking artifacts on the edges - really shows off the nice flat field of the Ritchey Chretien design, especially on an APS-C sensor.
