Vixen - ED81S 80mm ED Apochromatic Refractor Telescope Package with GPD2 Mount

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
camera mounting.

GPD2 Mounts



The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With
it’s solid steel R. A. and Declination axes and brass worm gears this mount
will hold up to years of heavy use. In order to assure accurate tracking for
astrophotography the worm, gears are especially machined to a very high
precision that minimizes periodic error.

The GPD2 holds almost 50% more weight than the GP2 and comes standard with
tripod and counterweight. It is easy to use and functions well for both the
visual observer and astrophotography. Motion is controlled by included
control knobs for accurate slewing. The polar altitude adjustment varies from
0° to 62° in altitude.
