Last night at last a clear night came where I could gather subs for more than a couple of hours. Since a bright moon was present and I was at home, I went for three nebulae through the hydrogen alpha filter in Cassiopeia. They were NGC-281, IC-59 and 63 and lastly IC-1805. They're known as the Pac Man, Gamma Cassiopeiae and Heart Nebulas. Each image is a stack of thirty 4-minute, twenty five 5-minute and twenty 5-minute subs taken through a ZWO 7 nanometer hydrogen alpha filter. An Astro-Tech 80mm EDT triplet apochromatic refractor, ZWO-533MM monochrome camera and Skywatcher EQ6R Pro mount were used to acquire the data. The seeing was mediocre and transparency was average. I'll be eventually assembling color images with more data through the other filters acquired from darker sites than my driveway without a bright moon present.
