Comet Holmes (11 December)
December 11, 20:00 UT
Canon EF 50mm lens (MK I), at f/2.8, ISO 800
20x30 secs hand-tracked exposures, (total exposure time 10 minutes)
Combined in DeepSkyStacker and processed in Photoshop
After 20 frames I was starting to lose the feeling in my fingers, at which point I figured it was a good time to stop. So, unless it repeats its 1892 behaviour and undergoes a second outburst sometime in January, this will probably be the last image I'll post of Comet Holmes.
Two naked-eye comets, a total lunar eclipse, and a daylight lunar occultation of Venus: 2007 has been a pretty good year for astronomy!
