A bit off topic since this is a DSLR image, but I did want to share with my buds on this forum. M31 seems to be a favorite this time of year. A full size image as well as exposure / processing details are at:

Wow, that's a beauty Jim. One of the nicest DSLR images I have seen for a long time.

Excellent processing. Too often DSLR images have only white stars.

Hi Jim,

Nice shot! The arms look a bit soft to me, but given the shortness of the exposures I presume they were too noisy otherwise?
