Last night I imaged five comets in Gemini and vicinity:
C/2007 N3 Lunin mag 9.6
C/2009 F6 Yi-SWAN mag 9.9
C2008 T2 (Cardinal) mag 11.6
144P Kushida, mag 11.8
116P Wild mag 12.7
These are all fairly easy imaging targets if you have current ephemerides to locate them. I use SkyMap Pro planetarium program, but you can get up-to-date RA/Dec coordinates for your observing time at

Enter the exact name (very critical!) in the box below the “Get ephemerides/HTML Page” box and click on it.
Epsilon 160 f/3.3, SXV-H9 camera binned 2x2. Exposures were typically 8 x 4 minutes.
