Chuck and Tom's Telescope ... Two 16's... .

Chuck's truss telescope, in the foreground, and
Tom's string-strut. Both 16" F4.5's. Now that
the OTAs are virtually complete, I like to test
them "under the stars". These two work perfectly.

Now to add the primary dew shields and altitude
bearings. I've yet to make the custom mirror covers.
