I plan on a roll off roof or a square building about 10X10' with a dome. Thinking about building the dome myself. Gulp!

Good for you! A LOT of people in the local club have done so and have done terrific work!

You MUST see the observatories these people have built! http://www.ultranet.com/~assne/

That will convince you to do it!
