SW Mounts -Alphabet soup
The numbering of SW EQ mounts is a maze.....
Numbers/ letters all over the place!
The best I can glean from the alphabet soup is:
-R = Refined (!) includes belt drive and encoders, as well as the USB (EQDir) port
-Rh = as above but with the Renshaw "Home" encoders.
Az- = Belt drive and encoders
