A 3" black-anodized (gold-anodized optional) aluminum "Extreme" focuser designed for use on large (10" to 16") Cassegrain Telescopes (NGF-XTc) with standard output threads and Newtonian Telescopes (NGF-XTn). The Cassegrain version includes a 2" Eyepiece Adapter. The Newtonian version includes a removable combination base (works on 10" radius up to a flat surface). The manual version of the NGF-XT lifts up to 8+ pounds and the motorized version up to 18 pounds. Manual "Nano Drive" control is approximately 13 times finer than most rack-and-pinion focusers. Regular motorized versions include a standard hand unit.
