Williams Optics Zenithstar 73

Reduced

This advertisement was offering a “package deal” that included a focuser and camera. However, I have decided to separate the components. I am selling the Zeithstar 73 by itself, along with a WO 73A field flattener and the WO rotator. You can purchase these components individually.

 The Zenithstar is an APO lens with a focal length of 430mm and an aperture of f/5.9. It is compatible with full-frame, APC-C, and M4/3 cameras. The scope has a dual spped focuser and built-in Bahtinov mask in the lens cap. 

The field flattener is adjustable, and the rotator allows manual rotation with degree markings. The scope DOES NOT come with the mounting dovetail, I'm using that, but it can be picked up for elsewhere for about $48.00

•  The scope sold new for $700, I’m asking $300

• The Flattener sold new for $278, I’m asking $100

• The rotator sold new for $129, I’m asking $60

 You can buy the package for $450 or the individual parts as listed.

 Thanks for looking
