II. Vixen Porta II Mount Description

The 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 Sky at Night says: "When moving the telescope around the sky with this mount, we found any vibrations quickly dampened down. The whole system was very stable, even when the tripod was at its maximum extended height"*. 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.

The “World-Standard” dovetail attachment system on PORTA II was developed by Vixen. This allows the PORTA II to accept various dovetail mounted optical tubes and binoculars.
