Horsehead Nebula from Anza – HaRGB

Only night I got to out this November was the Friday after Thanksgiving so even though the moon was up until around 2 am I decided to go for it. I captured three hours of HA data until the moon went down using my Astronomik 12nm HA Clip-in filter and then another two hours of RGB with the CLS-CCD filter.
