Featuring excellent rigidity, stability, and portability, the popular PORTA II alt-azimuth mount is chosen and used by a great number of users from amateur to professional.
The whole-circle slow-motion movement of the PORTA II provides smooth telescope operation at every pointing angle. Handle positions of both vertical and horizontal slow-motion controls can be altered in 45-degree increments. This allows a comfortable posture while using the slow-motion handles for various size optical tubes.
