Thanks for the info Karl.
This mount is such a big step up from what I'm used to, I'm happy to use it manually, or with the hand controller for the time being. It's so good to have dual axis control at my fingertips. All the old mounts were single axis.
At first it will just carry the ED80, but I have some 6 inch reflectors that I'll try at a later date. And of course your SW120.
