Observatory Plans

For the past 3 years I have been looking at different models and types of observatories suitable for backyard amateur astronomy. The dome with a revolving slit never made sense to me because of the effect on seeing of the escaping heat. So I finally decided on either a roll-off roof top shed, or clam shell. Sky Shed of Ontario, Canada has good pricing, and their selections of sizes and styles of wood-frame roll-offs are attractive and affordable – they even have do-it-yourself plans on CD. You can order them in various sizes, I”ll probably build one of the largest models — 10 x 12 or 10 x 14. Why not? Lots of room for visitors, desk, book shelves.
