The completed upper tube assembly. Joe's telescope includes the
use of a beautiful Feathertouch focuser by Starlight Instruments.
Note the Telrad base and Destiny curved-vane spider.
Completed, now, is the mirror box and upper tube assembly for Joe G's 12" F4.9 truss telescope. Once the OTA is tested (with the adjustable struts for focus) and is completed, it doesn't take too long to complete the telescope.

Note that the mirror box is about twice the length of my usual design. Joe asked for this modification as a way to control stray light in an otherwise light-polluted backyard (I think)!!

More to follow....
