Since writing that GC article, I have discovered that another GC has been added to the zoo: Minni 22 which is located at 17:48:51.4 -33:03:40. It is quite small, with a half-light radius of 1.1 arcmin, and in a very crowded part of the Milky Way in Scorpius. This is why it went undiscovered until 2018. As it happens, it is well placed here for tonight and as long as clouds don’t intervene I intend to have a go. By the looks of the DSS images, I don´t expect it to look like anything other than a MW star field but hope to pick up some of the stars mentioned in the discovery paper https://iopscience.iop.org/article/10.3847/1538-4357/aadd06/pdf
Won’t be easy, but we do these things not because they are easy but because they are hard.
