The Horsehead and Flame Nebulas in Orion

I got a second amazing night for imaging and despite it being a Tuesday I couldn't resist having a go at some RGB data and eating the lack of sleep. I combined the color channels with the hydrogen alpha data I collected on Saturday with the RGB images to get this image.

SBIG ST-8300m camera, Astro-Tech AT65EDQ 65mm f/6.5 refractor, Astronomik 1.25" RGB and Ha filters, Orion Nautilus 7x1.25" motorized filter wheel, Losmandy G11 Gemini-2 mount.

30 x 5 minute Hydrogen Alpha sub-frames for luminance
20 x 5 minute sub-frames for each red, green and blue filter
30 averaged darks
30 averaged bias frames
