Observed from Kitt Peak last night with the 11" Newtonian. I had hoped to get considerable exposure on comet 103p/Hartley, but was having declination backlash issues, so gave up after a while. This is a single 3m exposure with Canon XSi, cropped to about .5 degree square. In the upper left corner galaxy UGC 12381 is visible. North is approximately up. The comet was VERY extended, Melinda had trouble seeing it visually in the 11" until I cranked up the power a little. Oh well, it was fun tracking it down!
