ED “S” APO  
REFRACTORS  
Vixen ED 81S, ED103S and ED115S APOs  
These are Vixen's top-line APO refractors: made in Japan with  
new ED "eco-glass" (lead and arsenic free). 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.

Review of Vixen ED 103S (without reducer)  
The Moon was sharp with no color at all. 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.
