Used ZenithStar 81 f/6.9 Doublet APO + 0.8x Flat 6AIII reducer/flattener + WO M63 camera rotator

This is a ZenithStar 81 in excellent condition.  Both the optics and body are clean.  There is a tiny spot on the edge of the objective; you can see it in the photos in between the "c" in synthetic and the "f" in fluorite. 

This is a well-used scope; the Vixen dovetail bar is chewed up a bit, the focus tube has a straight line mark from being moved in and out.  See the photos.  Obviously, these cosmetic issues will not affect the performance of the scope. 

This also includes the 0.8x Flat 6AIII focal reducer/field flattener (a $269 value), which is in excellent, clean condition. 

This comes in its original soft-lined foam case, although the foam in the original WO case has been replaced.  It also includes a WO M63 camera rotator (a $129 value).  This item can be shipped.  

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.
