A 3" black-anodized (gold-anodized optional) aluminum "Extreme" focuser designed for use on large (10" to 16") Cassegrain Telescopes (EV-XTc) with standard output threads and Newtonian Telescopes (EV-XTn). A 2" Eyepiece Adapter is included. The Newtonian version includes a removable combination base (works on 10" radius up to a flat surface).
