Description

My first experience with my new QHY 268C on my SVX152T. For the camera I used an gain of 27 and an offset of 65

My main concern was that my image scale (0.64 arcsec/pixel) was going to be a challenge for guiding but my MX+ was up to the task over the 6 night of data capture. Guiding was averaging around 0.5 arc sec/px. A coastal marine layer, dew everywhere, and messed up flat frames all contributed to noise and the blotchy background. Big thanks to Ron Brecher (AstroDoc) for his expertise in getting the best out of this data.
