The skies finally cleared last night. Seeing as how there are four comets visible in the pre-dawn sky from northern latitudes, I dragged myself out of bed to put the K-3 through its paces. No problems other than one I had not anticipated: the multi-function button on the back of the camera is harder to manipulate with gloves now since they made the contact ridges a bit lower. The fact that it was -5C and my fingers were not working so well also did not help. Anyway, Comet Lovejoy was well-positioned so I snapped 33 x 10 second frames, stacked them in DeepSkyStacker and then post-processed the output in a variety of image editing programs. I used neither a remote release nor mirror lockup for this shoot since I wanted to test the damping of the shutter mechanism. No extraneous movement caused by finger release that I could detect. The K-3 is a great astro camera. - Jack
