NGC 6888 - Crescent Nebula in Ha (4 x 1200 second subs + 15 dark frames stacked in DSS). I continued my hydrogen alpha campaign tonight, with a couple more targets, including the Crescent. My goal over the next month or two is to continue capturing these nebulae in O3 and S2, and use those results with these Ha shots to produce color images. I may also test out some Ha+RGB image processing on a couple of the brighter ones like IC 1369a, the Elephant Trunk Nebula.
