Vixen - ED81S 80mm ED Apochromatic Refractor Telescope Package

When The ED81S was introduced last year it set a new standard for 80mm APO Refractors. The
combination of better color correction from the new ED glass and brighter images from it’s fast
f/7.7 focal ratio will satisfy the most demanding visual astronomer or astro-photographer.

The new ED glass is made from environmentally friendly lead free materials. The optical tube is
very stable yet light weight. The top carry handle also includes a 1/2-20 stud for piggyback
