This is 60 minutes of luminance unbinned (5 min subs, -23C) with the FSQ106N and ST2000xm, from my POD in Redlands, Ca. Seeing not good with 35-40 mph sustained winds out here this evening.

Re: Comet Holmes December 26, 2007 [Re: dietmar]       #2076555 - 12/27/07 06:06 AM Edit   Reply   Quote Quick Reply   Jim, beautifful photo, those galaxies give some sense of scale, this sucker is HUGE !!! 12-26-07 6:45-6:55 EST Bishop GA: After daytime temps in the 50s, a quick dew was settling almost immediately. Temps during the observation wer likely low 50s, very high humidity, nonetheless good clear seeing conditions. Comet Holmes was naked-eye, huge and diffuse, last night here in Bishop GA. First clear AND moonless night since we moved in, and a surprise to boot, since cloudiness was predicted. Tried at 38X with 106' TFOV in the 40mm Paragon with the 12" f/4.9, but the diffuseness is so great that I could only make out the central cigar-shaped portion, and not even the nucleus... -------------------- Good Seeing!
