ED 0.67X reducer:

This has been designed as an F5.2 reducer for our ED81, ED102 and ED115 refractors. At the same time it also provides a flat, illuminated 35mm image field. The multi-layer hard coating also reduces the reflections from very bright stars to a minimum.

The focal lengths are 419mm (ED81), 533mm (ED103) or 596mm (ED115). Exposure times are significantly reduced due to the higher light gathering power, and the larger field of view provides the possibility for also taking spectacular shots of extended star clusters and nebulae.

A T-ring and focal adapter are additionally required for connecting to a camera.

This reducer is not suitable for visual observing.

Can be combined with: ED81S, ED102S and ED115S

The resulting focal lengths are: 419/533/596mm (F5.2)

Accessories required for prime focus photography: focal adapter + T-Ring

Eyepiece projection possible? No

Visually observing possible? No
