William Optics ZenithStar 81 f/6.9 Doublet Refracting OTA Telescope Red

The William Optics ZenithStar 81 mm aperture Doublet APO Refactor is an extremely versatile telescope ideal for both astrophotography and general photography. It provides a sharp image to any DSLR, and pristine clarity for both visual observers and astrophotographers. This scope series is even capable of handling full frame sensors.

Zenithstar Dimensions

This air-spaced 81 mm series utilizes FPL53 glass for the clear detail provided and sharp colors. Similar to past models, this series also includes a 1:10 dual speed, 2.5-inch, R&P ultra robust focuser.

William Optics has crafted this series as an f/6.9 for respectable speed. On top of that, each scope in the series comes with a built-in, removable, clear Bahtinov mask for convenience in focusing.
