About the Vixen ED100Sf - 100mm Refractor Telescope OTA...
The big brother of the ED80Sf, this 100mm telescope offers great value for money by delivering a large aperture and great optics for observation.
Vixen''s apochromatic refractor has an extra-low dispersion (ED) lens which depresses residual aberration to achieve a high level of performance. The Vixen ED100Sf Refractor Telescope features the 2" Crayford focuser for smooth focusing without backlash. Coupled with a medium f/9.0 focal ratio, the ED "S" series provide a sharp, color-free image of high contrast.
