Final Construction Completed
Finally, Tuva North roll off roof observatory construction began in March of 2003. Because of the size of the 12.5" OTA, it required a minimum 8x8 square building. Details below. For details on the concrete base and LeSeuer Astropier, go HERE. Note that there are many images and it could take a while to load with a slow connection.
We previously laid 1 1/2" conduit from my house to my pier for fiber optic cable and electrical cable. Next we set six posts for the outer walls and outriggers.
First, 6 poles were set in concrete.
Next, the sub-flooring was installed. Sub-floor (2x8 treated).
Framing around pier. Note pier is isolated from sub-floor.
Gravel placed under sub-floor to reduce moisture and humidity.
Flooring in place.
Isolated pier with conduit, one for power, one for Ethernet, one for optional
cables to control scope and camera from computer hutch in corner.
Foil-backed wall board and the walls starting to go up.
Inside wall view with top of pier. Note AP mounting plate on pier and conduit for power and data.
The wall top plate is six feet from the floor, and height was determined by how low in the sky
the scope will ever be pointed.
Stringers going up. Top plate will be attached to rail on other side of wall.
