1970's Criterion 6" f8 reflector off of the dynascope. Original mount not working, so it's currently mated to a generic Equatorial mount. Mirror finish is very good, and images are very sharp. Original 1.25" focuser which works very well, and replacement finderscope, but original finderscope mount.
Custom dewshield and end cap. End cap doubles as light baffle for mirror end when viewing.

These were discontinued in the late 70's, and Company 7 has this to say about the optics:

A good measure of the success of the Criterion telescopes of this time were the high performance of their optics. While meeting the optical prescription of the proper curve is important, it is critical that the surface be polished to be consistently smooth as well.  The Criterion Primary Mirror substrate is Pyrex® which is arguably better than necessary for a small f/8 telescope, but it is a choice indicative of caring by management and not of pinching pennies.
