11/03/12: Imaging Session

March 12, 2012  •  Leave a Comment

It turned out clear on Sunday night, so there was an opportunity to start imaging some galaxies. I therefore chose M81 and M82 to start with. I managed to acquire two hours of luminence data with the intention of adding RGB data at a later date. The sky started to get a little hazy as the evening went on, but I was still gathering good data. The mount tracked perfectly, at times averaging a periodic error of 0.3 arc seconds with the QHY guider. I processed the final image the following evening after acquiring some dark frames for image calibration. I was pleased with the result, but look forward to adding some RGB data at some point.
