Here is a picture of M31 that I took during SSP. It is a stack of 10x10minute exposures, unguided on an AP1200 through a Takahashi FSQ106 and an SBIG ST8I. Processed using AIP4WIN.

M57 - Stack of 4x5minute exposures. RCOS 10" RC, AP1200, guided, with 
SBIG ST10XME. Processing with Maxim-DL and AIP4WIN.

Dom Morelli got these two shots of Mars...

...and these shots of the sun's surface...

...as well as M16, M17, and M27.

Ken Blumberg got this solar shot showing a nice Solar Prominence taken through Barlow Bob's setup.
