The electrical wiring underneath the Ground Board is protected....
The A-Frame was actually built to withstand much greater weight.... The Mirror Box/Cell/Mirror combined weight is around 800 pounds.

Now for the Rover, it will move itself....
The Rocker Box and Rover were built in parallel. I did not want to mar the Urethane coat trying to get a heavy steel structure built around it. The four steel sides bolt at their corners, with a scissor jack lift axle on one side and a trailer jack on the other for a three point drive system. The wheels are doubled to handle the weight of the entire lower scope and Rover. The trailer jack wheels are sprocketed to drive itself, I only need to steer.
Here is a closeup of the Drive Wheels....
The Drive system.... With a push of a button is moves....
Parked in the garage, just like a car....
超过800磅的DOB 自己上车
运往观测地组装
In use.... I had First Light one night before a star party with some close friends. They said they would be real understanding if the scope was not done, but failure was not an option. I had First Light, got some much needed sleep, and picked up my friends at the airport. The scope is just awesome to use. Very smooth operation. Using the 8" touchscreen right at the eyepiece just adds another level to observing when you can access good photos for identifying objects. Since it's a touchscreen I interact with the laptop which is bolted to the lower portion of a truss pole which is shoulder high.
Awesome Night... Having the spring-loaded wheels on the ladder really helps. Little effort is needed to move the 70 pound ladder yet it settles to the ground when you step on it.

此镜07年完成********11年最新修改Other new additions to OSP VII are; a new eyepiece holder!
Additional fans for the 1.5" thick, 6"minor axis, secondary mirror. These will blow across the face of the glass to remove the boundary layer of heat.
New Mirror box cover clamps to better seal in the cold.
The Mirror box received a new back cover to reflect the Sun's rays if I open the doors and it keeps the cold in.

Cool Breeze, the mirror box air conditioner is progressing! Here's a view of the control board with a temp controller, dual TC meter with TC's on a thick and thin portion of glass to show temperature uniformity, and, a dew point meter.
