Myself and Wayne after the last image
| Saturday March 2 2013 Trey McGriff, Wayne Peters and myself at the Kuhn telescope for another session with comet C/2012 S1 (ISON). About 18:30 Pacific Standard Time (pst) we focused the Kuhn on Castor, then Trey walked the telescope to the comet's position. At about 19:00 PST I started the 12x5 minute exposures. We had to hurry because we were losing the sky. The above photos were taken after the final image download. Telescope pointing almost at zenith. |
