The new and long awaited reducer/field-flattener from William Optics.

A good choice for the Megrez 90, Skywatcher 80 ED and other refractor telescopes with similar focal lengths. 

Provides superior off-axis performance and improved full field illumination with the above mentioned scopes than the existing ZS66SD Reducer/Flattener.

Features a 2" Nose-piece for connecting to the telescope and a Male T thread for connecting to the T-Ring or T-Thread of your camera.
