I finally finished the slab last weekend. I won't be able to build the observatory itself until Spring, which is good - it give me time to plan it properly. I have a book by John Stephen Hicks called "Building a Roll-Off Roof or Dome Observatory" which has been helpful.
The observatory will have a 10x14 foot footprint. The actual observatory will be 10x10, with a 4 foot warm room on the north side.
- How do you prevent the wooden rails from warping? They'll be painted or varnished, but are there better ways?
- I've heard that using fewer, but larger, rollers is better than more but smaller ones. (I'm going to use v shaped metal rollers running on gate track.)
- I'll insulate the warm room, should I insulate the observatory section?
Thank you for your help.
