Hydrogen alpha image (5nm bandwidth) of the Crescent Nebula; 6x20min for total of 2 hours, binned 2x2. Taken through 12" LX200R scope with STL11000M camera at Sierra Skies Observatory. Planning to combine this with the Red color channel, plus additional Ha exposures binned 1x1 for luminance. But as of June 1, we had tornadoes, rain storms, lightning, and hail in Sacramento (!), so still awaiting clear skies to collect the color data and remainder of the Ha data for the final image.
