The Upper Tube Assembly for Robert B. in Los Angeles is 99% complete. I just need to add the truss blocks. The UTA houses an "observatory grade" Destiny curved-vane spider as well as a Moonlite filter slide. The focuser is a Moonlite also.

The secondary is 1/30th wave mirror from Antares Optics.

Nice!
