The Vixen ED 100Sf now includes a Dual Speed Focuser. Vixen's apochromatic refractor has an extra-low dispersion (ED) lens which depresses residual aberration to achieve a high level of performance. Coupled with a medium f/9.0 focal ratio, the ED "S" series provides sharp, high contrast color-free images. For the astronomer that wants the best value for the dollar in a 4” APO, this is the one to get.
