Vixen ED103S Refractor Telescope with GP2 Equatorial Mount

The Vixen ED103S is an apochromatic refractor, which has fantastic contrast and a competent 4" aperture sufficient for viewing most of the planets and many stars. With its ED glass elements, chromatic aberration has been reduced to nearly undetectable levels, permitting a much more practical use of the higher magnifications quoted in the specifications than when seemingly identical in a normal achromatic refractor.

Vixen's ED Glass has brought refractors back to the forefront of premium telescope choices, to compete with the 8" and larger ubiquitous Schmidt-Cassegrains that, while bringing in enormous quantities of light, simply cannot compare to the contrast of the apochromatic refractor.

The included flip-mirror adapter allows either 90-degree or straight-through observing. With an eyepiece upon each end of the flip-mirror, you can quickly switch between the two as the declination of your object of interest changes its location in the sky.

The new lenses focus the full visible spectrum of visible light to a critical point much more accurately than past ED product. The ED103S lenses are almost free of chromatic aberration in all colors and are critically sharp edge to edge. The astrophotographer will be especially pleased with the high contrast images through this telescope.

The ED103S comes complete with 7x50mm finder, finder bracket, 2 eyepiece adapter, dual T-thread flip-mirror with dual 1-1/4" eyepiece adapters, 90 mm tube rings, carry handle and dovetail tube plate.

The GP2 equatorial mount comes standard with tripod and counterweight. It is easy to use and functions well for both the visual observer and astrophotography. The declination and right-ascension functions with 144-tooth aluminum worm gears allowing accurate tracking. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0-degrees to 62-degrees in altitude.
