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.

The strut single-ring (L) and full UTA. both have 4" secondaries and
curved-vane spiders. Note the focusers are 2-speed Moonlites.

The beginnings of rocker boxes and 24" altitude bearings. Each is a slightly
different width. The truss telescope is about 1" smaller in O.D.

A Visit from Steve and ...

Steve, and his wife Dian, came by from Berkeley, California
to pick up his 11" F4.6-ish telescope. We had a delightful
visit, talked telescopes and thoroughly enjoyed getting to
know each other. Thanks Steve. It was great fun.
