Finally decided to build a backyard observatory with a roll-off-roof. Documenting the process in the hopes it might help others wade through the process.
Very helpful to see your plannings for my own planned observatory in our backyard. Only one thing: I would always install a LAN cable. If you install the power line, it is almost no additional cost an work.
Since you're trenching for the power I'd put the ethernet cable in anyway, even if it's unterminated. The cable isn't very expensive and it's always there if you want it.
I really enjoyed this video! You didn't mention how much it cost you to remove the trees, or did you remove them yourself? Looking forward to seeing the next video!
