*68 Cas
Image session: Monday July 13th 2020
The LRGB image is made up from a single set of RGB at 300s and six luminescence of 300s and two of 600s. The camera was cooled to -15°C, unfortunately due to the problems I was having with Sequence Generator Pro and the Sesto Senso 2 focuser I did not have time to take the correct temperature darks, so used the -7°C darks taken a couple of nights previously, this was the same with the flats and bias calibration files. The images were processed using AstroPixelProcessor.
The image was then plate solved in Astrometry.net (https://nova.astrometry.net/).
