Porta Mounts

The Porta II is a solid alti-azimuth mount with a 20lb payload capacity, features Slow Motion Flexible Handles to minimize vibrations and keep your view sharp, very useful in searching and tracking celestial objects. 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. 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 “World-Standard” dovetail attachment system on PORTA was developed by Vixen. This allows the PORTA to accept various dovetail mounted optical tubes and binoculars.
