Description

First test shots of M42, the Orion Nebula, M43 De Mairan’s Nebula, Sh2-279 Running Man with the ZWO ASI071MC cooled CMOS camera. No calibration frames, just 17 stacked 300 second light frames, with the sensor cooled to -10C. And last night was not very clear, scattered clouds, fairly poor seeing. I can't wait to test things out with some really clear and dark skies. I will say, so far, with only a few hours of use, I'm impressed with this ZWO color camera, with how much this camera can pick up, bringing out some very faint nebulous areas. I know it has a very wide/high dynamic range. That's one of the things I was looking for in an OSC camera. For this M42 test I used a Gain of 0 and Offset of 8, the minimum recommended by ZWO for long exposure times and HDR (high dynamic range). (William Optics GT-81 + 0.8x Field Flattener/Reducer f/4.7, ZWO ASI071MC cooled CMOS camera, iOptron CEM25P EQ mount, 30mm mini guide scope with ZWO ASI120S-MM guide cam, INDI/KStars/Ekos observatory control).
