Comments on: Messier 27 - the Dumbbell Nebula http://www.raben.com/weblog/2006/07/28/messier-27-the-dumbbell-nebula/ Occasional observations about astronomy, astrophotography, and software Mon, 01 Dec 2008 23:06:07 +0000 http://wordpress.org/?v=2.3.2 By: Vern http://www.raben.com/weblog/2006/07/28/messier-27-the-dumbbell-nebula/#comment-1303 Vern Sun, 30 Jul 2006 00:46:28 +0000 http://www.raben.com/weblog/2006/07/28/messier-27-the-dumbbell-nebula/#comment-1303 Thanks all! I'm amazed at the ability of current software tools to coax the subtle colors and details from a bunch of dim, unimpressive images. The trifid nebula and the dumbbell are great to photograph as they have wonderful contrasting colors. It looks like 3 minute exposures and stacks of 15 or more images are needed. Unfortunately, that means an hour or more of manual guiding per image til I upgrade some equipment and write or buy some guiding software. Thanks all!

Missed focus by a tad, I'm too dazzled by the size, shape, texture, and all the colors, even the stars. As for the wallpaper, I still use your moon shot from back in January (moon-2006-01-10-0343.jpg). I don't see it in your archives but it is similar to the gibbous in February 2006.
