The Vixen Mini-Porta comes equipped with two fine adjustment handles for whole circle slow motion in both directions, very useful in searching and tracking celestial objects. In addition, these are great mounts for terrestrial viewing. Vixen's gear drives make it a simple matter to precisely track a planet on the horizon by simply turning the elevation and or azimuth control handles. This sturdy observing base weighs just 6 lbs but will hold scopes up to 10 lbs. The “World-Standard” dovetail attachment system on the Mini PORTA was developed by Vixen. This allows the Mini PORTA to accept various dovetail mounted optical tubes and binoculars.
