Details:
Not a great photo, but useful to estimate what one would expect to see with limited equipment. ISON is in the white circle (see for comparison the attached matching Stellarium screenshot), very very faint as it appears to the eye of my equipment. I've copied into the photo the magnitude of some nearby stars as per Stellarium data.
Non tracking 2sec exposure, ISO 6400, f 5.6, 300mm lens, Canon 600D, single shot, processed with Microsoft Picture Manager. Photo taken on October 22 before dawn.
