OK, I had a few clear nights back in the first week of January. Transparency was very good, but seeing was well below average with some upper level winds, Clear sky clock had it light blue to grey, which was accurate. Nonetheless, I put my 16 RC on Messier 1, the Crab Nebula. The moon was around 84% illuminated, but going down in the west. This was taken around 1:45am est, on January 6. My focal length was 3250mm, and I had the Sony A7s using the OPT Quad filter. This turned out surprisingly well. Unguided, a stack of 8 - 92 second exposures. I am not thrilled with the background, it is a bit uneven and a tad too dark, but the Crab Nebula, a supernova remnant, really pops.

Real nice image maadscientist...!  I didn't think the OPT Quad could produce such a nice image.
