The Vixen PORTA Manual Altazimuth Telescope Mount is very likely the finest light-duty altazimuth mount ever created. Beyond workmanship you don't see at this price, the PORTA's main trick is its dual movement. It features precision, geared altazimuth movement as well as rapid free movement, but you don't have to engage/disengage anything to switch from one to the other! When you want rapid movement, simply grasp the telescope's tube and move it where you like; the mount immediately accommodates your desire. When you get it pointing in the ballpark and want to refine its position, use the dual-axis geared slow-motion controls. PORTA's reputation has become that it is the only altazimuth mount to rely upon for high-magnification viewing free of annoying shaking.
Porta's quick release dovetail mounting slot with locking mechanism and safety screw facilitates quick and secure assembly/disassembly of telescopes, and the plates are the same as for Vixen's GP, Great Polaris, Sphinx, and SXD mounts (as well as Celestron's CG-4, CG-5, and Meade's LXD55/75).
Note! Dovetail plate not included.
