ASTRO: IC 5146
Saturday night was a wash due to a faulty battery (which was a shame because
not only was the sky very clear that night, but the seeing was the best I've seen in a long time, with low humidity to boot), but Sunday was pretty productive. I know most of you take hours and hours of images of one object, and I do plan to get there some day when I have a proper filter wheel. But last weekend presented such fantastically clear skies, that I had to try as many objects as I could. I did concentrate on a couple of objects though, on of them being IC 5146, the Cocoon Nebula. About the photo: 6 five-minute exposures at ISO 800, for a total of 30 minutes, one five-minute dark Equipment: Modified Konus 200 f5 Newtonian with Baader coma corrector 80 mm Orion shorty for autoguiding with the starshooter autoguider Losmandy G-11 Gemini Go To on the large Losmandy tripod Hutech Modified Canon T1i with UV Infrared cut astronomy filter (allows transmission of Ha) Taken On Sunday, September 5, 2010 at Taylorsville Lake, Anderson County, Kentucky. Processing softwa Maxim DL 5.08? Deepsky stacker Adobe Photoshop CS2 extended. Enjoy, George |
