A few Pix
Harder to take than I thought but here you go.
Frontal shot, door open. Ob is on a raised floor over the slab, about 400mm above it, you can just see the pier inside. Pier goes through the floor and down onto the slab. Roof slopes West (left) East Right. West side is longer and has a central flat section that overlaps the east by 100mm. You can also just see the tops of the wooden rails the roof sections slide out onto both sides.
Inside looking up into the roof and the overlap area opened up slightly. The hasp and clasp is one of the lockdowns (4) and you can see the slope of the roof and ply ( only 4mm exterior ) Probably about 60 screws holding it all together so it acts like a braced diaphragm construction.
150 x 25 is strengthened by the steel bar over a join.
Inside corner shows the 150 x25's braced (behind the black cloth) and a cross member in the roof. I've hung my two PC screens up on the back wall, gets me some desk space below. Black cloth just keeps stray light suppressed.
Hope this gives you some ideas. This was a cheap Chinese import shed, only about $400 so is pretty flimsy but the wood gives it the strengthen and the tin keeps it dry. I may have to add a soft seal strip between the two roof sections overlap, I've had a few drips come through but I keep the scope and mount under an old sheet and then a plastic cover.
Last shot is the scopes and pier. They just get in under the roof by about 100mm or so. If I was doing it again I'd make the roof a bit higher, maybe 300mm in the centre, not 150mm. Other than that I'm happy with how it works.
