With the moon very low down and a clear(ish) sky I decided to have a try at M53. The guiding calibration adjustment seemed to be maintaining the improvement shown by the earlier test. This one is much less dense than M3 so is a closer crop than my previous image. With M13 & M92 nearing my window it looks as though globulars will be high up the list for a while. Details: 10x 150 second exposures @ iso400 with CLS in DSS & CS2.
