Thanks Humayun!
I went down to York today, and the 10inch is huge! I think im now set on the 8", since I think it will be more portable and I'll get a whole lot of use out of it. Didn't have my car and had to get back to work, otherwise I would have brought it right there and then.
Some other questions I have.
1. What would constitute as a good eye piece? Is it brand? Is there a place I can read reviews like how I do with SLR lenses for my camera before I purchase?
2. There seems to be a couple of different collimation tools about. Is there a recommended one?
Thanks!
