Hi Graham
Welcome to IIS

I am sure you will find this site friendly and helpful. As to the GEM.You need to have the right counterweight at the right position to balance the scope. Its essential. With the axis pointing to roughly SCP, release both dec and RA lock and "twist" (thats the only word I can think of) the scope until it point to north where Saturn is. You might find the counter-weight bar almost horizontal now. Lock both axis and take over by slow motion control.
Cheers
Vincent
