Tom's OTA -- Almost Complete . . .

The mirror box. Note the black anodized struts. All aluminum, except
for the mirror cell, will be black anodized or powder coated.
This telescope has the Easy Transport Telescope option
Note the bottom half of the struts, about 21" long for
this F3.92 focal length. Nice 'n small!!

And with the Intermediate Ring in place. This
not only allows the struts to be one-half the length
but adds some rigidity to the assembly.

The "top half" of the struts.
Add the top ring, with focuser, spider and
secondary, and the OTA is virtually complete.

The total strut length is 42.5"
