The Vixen Porta II is a solid altazimuth mount with a 20lb payload capacity and features Slow Motion Flexible Handles to minimize vibrations and keep your view sharp. This is very useful in searching and tracking celestial objects.
The Porta series of mounts are designed for small optics. They have high-quality roller bearings with an adjustable slipper clutch. This allows the optics to be quickly adjusted to the desired object.
The fine adjustment is made using rotary knobs, which sensitively adjusts the optics in elevation and azimuth, each by means of a worm gear.
The mount is very light and compact and therefore perfect for travelling.
The mount head is easily removed to allow for a switch to a heavier tripod. In addition, this is a great mount for terrestrial viewing. With no locks or clutches, our gear drives make it a simple matter to precisely track a planet or a ship on the horizon by turning the elevation and/or azimuth control handles. The Porta II Mount features slow motion control of both axes, solid central bolt for easy tripod change, flex handles and accessory tray.
