Hi John
OK, I see what you mean by the 6 screws that hold the rings. And you're right, I think the first 3 would be easy enough, but the one at the bottom of the primary mirror tube - gee - I get the sweats just thinking about it

.
I may just wait a bit with that one - let me get my confidence up
On a much better note, just got back from some viewing. OK, WOW! Great scope. My first was M42 - WOW! Saturn got a good viewing as well WOW!
And everyone is right, it's all about getting out there and trying differnt lenses and learning. So thanks all

- still a long way to go, but I'm going to enjoy the journey.
Martin
