Mars on Oct 25
Since I was up taking images of 17P Holmes, I captured Mars as well just before shutting down. According to the S&T Mars Profiler, that should be Mare Cimmerium extending from the left to about midway across and then Mare Sirenum extending onward to the lower right.
Image taken with Celestron Nexstar 11 telescope, Televue 2.5X Powermate, and Phillips Toucam 840K webcam. Location was from Louisville, CO. Sky was clear, no wind, temperature 48°F, very good transparency, and turbulence 7/10.
