Hi Mark,http://www.gralak.com/Astro/NGC6946-LRGB.jpg-Ray Gralak Thanks! Equipment: AP 1200 GTO (makes this ON topic!) RCOS 10" Ritchey-Cretian scope. SBIG ST-8E + CFW8 + AO-7. Exposures: 10 x 10 minutes Luminance 3 x 5 minutes Red, Green, and Blue Processing: MaximDl was used for image acquisition I used Photoshop 5.5 to do color combination (LRGB). Mild stretching and an unsharp mask was also done in Photoshop, as well as the "repair" of a couple of minor blooming spikes on the two brightest stars. -Ray

Hello Ray,

Very nice image. I assume that this image was acquired at Mt. Lassen? It would be interesting to know where each of the images on your site were taken. Particularly, which ones were taken in your backyard vs at better sites. I am used to traveling to dark sites for my film astrophotos, but as I get older and lazier I want to stay closer to home. I am starting a backyard observatory and am curious just what kind of results can be had from light polluted skies (mine is not too bad, at least I can still make out the entire little dipper). I got in on the next run of 1200GTOs, so at least getting objects onto the CCD in my backyard skies will be less of a problem (currently I use a GM200). Bob Luffel

Thanks. I have been meaning to reorganize my web site into a better format. When I do that I will indicate where each image was taken from. But the majority were actually taken from my backyard in light-polluted San Jose, California. -Ray
