A unique project we designed and manufactured was
a 40 cm telescope for a balloon borne experiment. This
telescope used Invar spacers to minimize focus shift
with temperature and had special mirror supports to
allow the telescope to look below the horizon.
Recently, we have designed and manufactured four specialized
telescopes and instruments for measuring astronomical
seeing.
These telescopes are also customized versions of our
standard CCT-16 but have special optics, invar spacers,
a full aperture optical window with dew shield, are
hermetically sealed, and breathe through a cannister
of dessicant.
