A 12" F4.9 for Joe G. in
Palos Verdes, CA.
The final stage of building the OTA before finishing it completely. I calculate the length of the OTA and use "test struts" under the stars. If any adjustments have to be made -- I can move the struts up/down to bring all my eyepieces into focus.

Once complete, I finish the OTA and move on to finishing the rocker box. The scope is about 10-14 days from completion.

Ultimately, this scope will be a "truss" optical tube assembly.

Stay tuned.....
