Hi Robin,
Glad to hear you got a 12" scope. Although I have no trouble when I really want to get so my 12" Tube dob out the back yard or to a dark site, there are times that I do shrug and grab my smaller scope. Some people say a trolly is easy to use, but I find it difficult to trolly the base and tube at the same time. I think they must mean trolly the tube seprately?
Anyways...I love my 12" Dob to death...It really has opened up the sky in an otherwise useless suburban situation with so much light pollution. I am yet to see what it can really do at a Dark site.
Good luck with it & I am sure you will work at a routine for moving the thing
