This 8′ x 12′ roll-off roof observatory was built in 2009 for a permanent installation of my C1400 Celestron scope on CGE mount. In 2024 the mount was upgraded to a Skywatcher EQ8pro.  A solid pier is mounted on a concrete pile foundation isolated from the floor.  Of course, other scopes and imaging equipment are mounted depending on the configuration needed.  The observatory is convenient and I can start imaging in 10 minutes and run it remotely from the  warmth of my home.
