Vixen ED 100Sf APO Refractor with Sphinx Mount

The Vixen ED 100Sf APO refractor features high-grade glass and quality components. Coupled with a medium f/9.0 focal ratio, the ED "S" series provide a sharp, color-free image of high contrast. For the astronomer that wants the best value for the dollar in a 4" APO, this is the one to buy. Apochromatic refractors from Vixen have extra-low dispersion (ED) lenses that depress residual aberration to achieve a high level of performance.

This package combines the easiest to use Sphinx mount with the most affordable large aperture APO telescope. You'll find yourself looking deeper and deeper into space as you gain familiarity with the Sphinx mount and more than likely try a little astrophotography. Certainly the Sphinx gives you full capability for both.
