Not been that active for a while, mainly due to the weather, but managed a quick session on 19th March, when I looked at M3. 

Photo below is a stack of 100 30 second images taken with a ZWO 071 Pro camera (gain = 200, sensor cooled to -5C). Stacking was with DSS, and processing was with Nebulosity 4 and Affinity. Telescope used was a Takahashi 102 TSA with 1x flattener and UV/IR filter. Autoguiding/dithering etc. was all done via ASI Air Pro and the mount used was a Losmandy G11.
