Well, we finally painted the observatory. Here is the front view. The front door is still to be painted white, so I'll paint it with spray paint for a nicer finish. The wall temperature is really cooler now with the white paint applied to the walls. White being a nice reflector repels the sun light nicely and keeps the inside cooler now.

The east side of the building with the air conditioner and TV antenna mounted on the side wall.

Looking at the south and east walls.

Looking at the west wall. I installed the skirts on both sides of the rooling roof, which helps to keep wind and dust out of the scope room.
