There are probably lots of threads about building a roll off roof observatory.

I have built 2 before. The roll off roof on both is a bit hard to operate. On one in particular. So I need to improve that design a lot so it rolls off easily.

I am not looking to do a remote observatory as this will be a backyard observatory on a residential block. So about 4 x 2.8 metres or so.

I'd like to mount 2 scopes to keep the idea alive of maximising imaging time when the weather is fortuitous.

Any links or suggestions to builds?

Last I looked into this electric rolling gate tracks from Bunnings seemed to be a good approach with a garage door opener to power the roll off.

Lightweight treated pine or metal batten construction would be the frame on a simple 100mm slab (not sure deep piers are really that necessary).
Cladding will be insulated colorbond sheeting (miniclad?).

Any tips?
