Cold and clear night: M45 and M33

[iantaylor2uk]

Managed a couple of quick photos last night, which was very clear, but also very cold. 

Took 240 thirty second images of M45, and then M33 (which was fairly close to the moon). I stacked the best 90% of the images, and used dark, flat and bias calibration frames. Stacking was with DeepSkyStacker, and then I quickly used GraXpert to get a final processed image. Fairly pleased with the M45 image but probably need a lot longer on M33. 

The camera used was an ASI 071 MC Pro and the telescope was an FRA 300 (focal length 300 mm, objective lens diameter 60 mm). I also used an IR/UV filter.
