Re: [guide-user] comet ISON

Hi Lawrence,
I too agree with your coordinates, but I wonder if the comet is bright
enough to show in a 60" image. GUIDE shows me that its magnitude should be
about 15.2 (although I don't remember where I got my mag data from).

Hi Lawrence,

Position appears to be ok. 60sec exp might be a bit too short. I use
TV100 with ST-7 and 5 min is much better, though it is quite small and
can be hidden when a brighter star is closeby.
