Vixen Reducer 0,67x ED81S/ED103S/ED115S (5462)

The ED 0.67x reducer is designed as an f/5.2 focal reducer for Vixen’s ED81, ED103, and ED115 refractors. It provides a flat, illuminated 35mm image field, making it ideal for astrophotography. The advanced multi-layer hard coating minimizes reflections from bright stars.

When used with the ED81, ED103, or ED115, the resulting focal lengths are 419mm, 533mm, and 596mm respectively (all at f/5.2). This reducer increases light gathering power, shortens exposure times, and offers a wider field of view, making it perfect for capturing extended star clusters and nebulae.

A T-ring and focal adapter are required to connect a camera. This reducer is not suitable for visual observation or eyepiece projection.
