Why Buy a STS?

With the high price of apochromat ("apo") refractors, many observers find it prohibitive to own a large aperture planetary instrument, and with the advent of high quality newtonian mirrors, a properly constructed newtonian can rival and in many instances exceed a similarly sized refractor in planetary detail;

Back in 2002, when Teeter's Telescopes was first established, all of our telescopes were designed to be "Planet Killers." We still include many of the same contrast boosting enhancements including a black velvet baffle internal to the mirrorbox, black velvet baffling across from the focuser, low-diffraction spider vanes and small secondary mirrors that yield central obstructions below the key planetary threshold of 20% (Secondary Minor Axis/Primary Diameter);

These small to medium aperture, long focal length, scopes represent the ultimate in planetary performance in a package that is transportable and comfortable to use all night long;

Small to moderate apertures provide stunning planetary and lunar details to fascinate even the most experienced observer;

The slow focal ratios (>F/6) do not require the use of a coma corrector;

Our Truss Ring makes these apertures and focal ratios a breeze to set up and transport;

Your choice of Lightholder Optical (LO) or Zambuto Optical Company (ZOC) primary mirrors provide primary mirrors of the highest quality currently available. Antares Optics provides finely crafted secondary mirrors that are a perfect match for either of the above primary mirrors. Magnifications of 40x-50x per inch of aperture are achievable on nights of steady atmospheric seeing conditions;

Lightholder Optical (LO) primary mirrors come with printed test reports, while Antares Optics secondary mirrors come Zygo tested. No test reports are provided with the ZOC primary mirrors, but ZOC's reputation in the industry for the highest quality optics is legendary (no test reports need apply!).
