Here's one I've just got round to processing.  The bright globular cluster Messier 53 in Coma Berenices has a fainter and much less dense globular neighbour NGC 5053. The night of 24th February 2020 was briefly clear, and in between passing clouds I was able to capture just enough data for this image. QSI683 on TMB105 refractor with SX AO unit and TSFLAT2 flattener. Luminance 7 x 5 minutes, RGB respectively 5, 4 and 3 images of 5 minutes, all unbinned. This image slightly cropped for better positioning of the targets - they were off centre because of the guide star position.

That's a great shot.   

 I always like two flavours of DSO in the same frame, and the range of spectral colours within the star field adds to the impact.
