IC1805/Sh2-190 - The Heart Nebula (HaRGB)

17:25 8/11/2006 UTC

Transparency was lousy and bright moon was up while imaging this HaRGB composite. If the conditions would have been better this might have been pretty good shot. I got good two hours worth of exposures for Ha and just after finishing focusing for RGB, laptop battery went dead... I took unguided 17 minutes of RGB before I had to finish. Because of full moon, blue channel was very noisy and I didn't get good star colors. I have a lot to learn making HaRGB composites. OIII would be nice also. However, time to move onto next target...
