Interesting that the TECNAR uses some of the same castings as the OBSERVER, but can be set-up in true equatorial mode. In use, Moonwatch scopes are simply transit telescopes, for recording the elevation of the satellite as it crosses the meridian, as timed by the observer. But the TECNAR can be used as a full astronomical telescope. Cool.
I've discovered that the mirror in my OBSERVER needs re-aluminizing. I"ll be paying NOVA optical a visit soon.
Yes, I have both the Tecnar in its (cardboard) box as well as the Observer, and there's no question that they share common base and pillar castings/parts, though my Observer has four holes in the base that the Tecnar does not. Also, the tube assemblies of those two are completely different, so who knows if they were made completely by the same maker or if the castings went to more than one outfit. My Tasco satellite scope differs in other ways, as it's an elbow telescope on a small tripod, both with painted grey wrinkle finish. It came in a flashy purple cardboard box with gold lettering. Quite a few companies made them, seeing the market opportunity, and plans were published for amateurs to make their own.
Here's the link I posted recently about Fred Whipple's Micronta satellite scope, now part of Harvard's Collection of Historic Scientific Instruments:
Whipple (of "icy snowball" comet fame) was the founder and director of the Smithsonian Astrophysical Observatory's Moonwatch program, based at Harvard, and he had to convince a very skeptical military and others that amateurs could make valuable contributions. I don't know if he had other Moonwatch scopes besides the Micronta, though I suspect he did.
