Description
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 for any DSLR, and pristine clarity for both visual observers and astrophotographers. This scope series is even capable of handling full frame sensors.
This air-spaced 81 mm series utilizes FPL-53 glass to provide clear detail and sharp colors. Similar to past models, this series also includes a 10:1 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.
These OTAs include a dual-side dovetail compatible with Vixen and Arca Swiss stylings.
