manual abstract
These scopes have faster focal ratios and a more compact length compared to the prior ED 80S and ED 102S telescopes. In fact, the big ED 115S is shorter than the old ED 102S! The new optics are especially good at suppressing the dispersion of violet light — this avoids halos and blooming around images of bright stars. Coupled with a medium f/7.7 focal ratio, the ED "S" series provide a sharp, color-free image of high contrast for both visual and photographic applications. The big Vixen 60mm drawtube means these refractors can handle the full line of Vixen drawtube accessories. Vixen finishing touches include standard flip-mirror, carry handle, and focus tension/lock. Works great with any Vixen equatorial mount. Telescope Specifications with and without ED 0.67x Focal Reducer Telescope Model # Accessories Obj.

The contrast was great with Plato and the Alpine Valley showing a wealth of detail as did Copernicus. Out of curiosity, I set the zoom at the 8mm setting and inserted it in a 3x Barlow (that's almost 300x) with no image breakdown on the Moon and I actually felt I could have gone higher. — Johnson, Pernel.
