The Horsehead and Flame Nebulas
luminance: Ha 5 x 600 sec, RGB 10 x 150 each binned 2x2 autoguided on 12/01-08/07.
Equipment: 6" f/3.89 newtonian astrograph with MPCC coma corrector and SXV-H9 camera mounted on a G-11.
Processing: Combined in Maxim D/L, processed in Photoshop CS with lots of hide-all layer masks and with Noel Carboni's Astronomy Tools. I also blended a the red channel with the Ha to keep the color data from getting washed out a la Robert Gendler's blending technique.
