Vixen ED81S Apochromatic ED Refractor with Dual Speed Focuser, Dovetail Adapter and Tube Rings
Model 75864

When the ED81S was introduced, it set a new standard for apochromatic refractors. The combination of better colour correction from the new extra low dispersion (ED) glass and brighter images from its fast f7.7 focal ratio will satisfy the most demanding visual astronomer or astro-photographer.

This 81mm aperture tube is extremely compact and lightweight and comes with the Vixen dual speed focus system as standard.

Light gathering power is 134x and the unit is supplied with tube rings and dovetail mounting plate for quick and easy connection to any Vixen mount.
