"It's all glory" !! OK, Dennis, here it is.
I took the scope out last night for a go. It took me a while to find the right balance, but I'm happy to say it's everything I hoped. I can use any 1.25" eyepiece with ease, and the scope stays put; but it is easy to move with the view, even at 240x. Just what I wanted.
BTW, the scope is a 6" f/8 with Parks primary and Moonlite focuser. It has a curved-vein spider and very good secondary. The scope gives lovely views, best I've had of some things.
