I need an observatory and my only option is to use an existing flat roof single garage.
The garage has a good solid concrete floor so I am thinking:
- build a platform for the pier on the floor with concrete engineering blocks - it will need to be around 90cm high.
- Bolt a pier onto the platform
- Build a raised walkway around the pier platform for access - and probably build some stud walls around (Security, Keep Dust out, stop me falling off the walkway etc)
- Cut a hole in the roof and have the scope just able to pop out at around 30 degrees. I'm surrounded by houses and don't image below this anyway. I need to measure accurately but I estimate a 40" square opening should do it.
I'm not worried about vibration because I'll be in the house during imaging
My main challenge is how to make a weatherproof opener in the roof with it being flat. I need to keep it low profile because we are in a conservation area and the planners will kick off about it if its noticeable. So I'm aiming to keep the profile as flat as possible - 4" max height above the roof plane.
Any ideas would be welcome, I think my options are a sliding panel or two hinged panels.
