Patrick, Very good. I am impressed Rodger -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Patrick Wiggins Sent: Friday, October 01, 2010 5:11 AM To: utah astronomy utah astronomy listserve Subject: [Utah-astronomy] Comet Hartley Tonight I noticed I'd just passed 103 nights of imaging in my observatory this year. 103 reminded me of Comet 103P/Hartley (yeah, my mind is wired weird). So to commemorate the event I shot a series of 13 ten second exposures of the comet each spaced 5 minutes apart between 0901 and 1004 UTC (0301-0404 MDT) and strung them together in an animation. Specs: C-14 @ f/5.5, ST-10 binned 3x3, C filter, FOV ~ 18' x 26'. North is up, east to the left. http://users.wirelessbeehive.com/~paw/temp/103PHARTLEY20101001.GIF I didn't do anything "heroic" to the raw files other than apply a master dark and master flat and remove several hot and cold pixels. If anyone would care to have a go at bringing out more cometary structure I'd be happy to email them the originals. patrick _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
