Here's my effort to assemble the pic from the color set. jb http://www.slas.us/gallery2/main.php?g2_itemId=1123 --- On Sat, 2/21/09, Patrick Wiggins <paw@wirelessbeehive.com> wrote: From: Patrick Wiggins <paw@wirelessbeehive.com> Subject: Re: [Utah-astronomy] Lulin FIT files (color) To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Saturday, February 21, 2009, 5:25 AM Here are more, this time deeper (2' @ 3x3 instead of 1' @ 2x2) and including color. http://users.wirelessbeehive.com/~paw/temp/LULIN2009FEB21C.ZIP Contains 5 clear, 2 red, 2 green, 3 blue, a master flat for each color and a master dark for all. As before I tracked the comet so the stars are trailed. Honestly, I'm not sure how one goes about combining all the colors for a moving target. But some how I've got a feeling Tyler knows. :) Carpe Noctem, patrick On 21 Feb 2009, at 02:42, Patrick Wiggins wrote:
I got 6 "quick and dirty" 1 minute exposures. All washed out the way them came out of the camera (the comet is bright) and since I guided on the comet (which is moving quickly) the background stars are trailed.
Should anyone care to try and salvage something from the FIT files you'll find them at:
