The PORTA II alt-azimuth mount is renowned for its outstanding rigidity, stability, and portability. Paired with a 80mm optical tube equipped with an ED (extra-low dispersion) lens, this setup effectively minimizes color aberration at an elevated level, ensuring a remarkably clear and highly contrasted viewing experience.

Slow Motion Handles

PORTA II boasts a whole-circle slow motion movement, ensuring seamless telescope operation at any pointing angle. The handle positions for both vertical and horizontal slow motion controls are adjustable in 45-degree increments, offering users the flexibility to achieve a comfortable posture while operating the slow motion handles with optical tubes of various sizes.

Dovetail Plate Attachment

Vixen's widely acclaimed dovetail-plate system facilitates effortless interchangeability of numerous optical tubes, accommodating sizes of up to 160mm in outer diameter. This versatile system allows users to seamlessly mount and dismount various optical tubes with ease.

Accessory Tray

A dedicated accessory tray is designed to securely hold small items like cameras or eyepieces, offering practical convenience during nighttime observations.

Compartment for Tools

The positions of slow motion handles and the level of friction on the axes can be fine-tuned using the tools conveniently housed in the compartment beneath the rubber covering. This ensures easy access to the necessary tools whenever adjustments are needed.

Detachable Tripod System

The mount head and tripod can be easily detached using a single fixing bolt, providing a convenient solution for transportation and storage purposes.

Friction Control System

The optical tube is maneuverable by hand, and the friction mechanism ensures it maintains its position at any stopping point. This feature enables users to manually direct the telescope toward specific celestial objects they intend to observe with precision and ease.
