Time for another update:
The Royce 12.5" f/4 conical mirror has arrived! It feels surprisingly light, which is nice. I have ordered an ultra precision 1/30 wave diagonal from
Antares Optics to go with it.
Now that I have the mirror I have been able to balance the parts and calculate truss lengths, and the OTA is rapidly taking shape. Finished installing the truss poles today!
