ASTRO: M101 colour
Here is the colour version of my M101 shot.
Taken from the middle of Berlin with a 10" Meade ACF at f/5.7 on a G11 mount, SXV-H9 camera, 109x5 minutes for L and 12x5 minutes binned each for RGB (3x5 minutes Ha mixed into red). The picture can also be found at http://ccd-astronomy.de/temp/M101colourgut.jpg Stefan |

Even at 1" per pixel they really didn't show but when I went to 0.5", even though seeing wasn't up to it, then they came through. Still don't understand that. I'd have thought using some Ha would have helped more. Guess not. At least you have imaging skies. 51 days and counting without imaging skies even for one frame. Ducking tornados seems the hobby of late. I've got dozens of downed trees to work on but with all the rain the mosquitoes are so horrid no way I can work on them without at least three blood transfusion IVs running while I work to replace what they suck out. Never seen them so bad all day long. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
