We had an unexpectedly clear night last night and I managed to get a full 3 and a half hours total imaging time on the M53 region with the Sky 90/M25C.  There’s a bonus of another globular cluster at the top of the image.  200-second sub-exposures, and 63 of them in total produced this deep-sky image of the area.  I did the processing on the version shown here – Noel will do a much better job on the data when he gets round to looking at it 🙂
