Matt, I am interested in obtaining a Baader clicklock for my University 2" prism. I have measured the male insert thread to be 55.6mm and 4 threads in 3mm, so assume it must also be M56x0.75. From your information the Baader Skywatcher adaptor (# 2956256) is M56x1 so have I the same problem as Col, needing an adapter between the two slightly differing threads. I wish there was some standardisation between Eastern manufacturers!
Col, if you decide to go ahead - let me know and I will get an adaptor as well.
