Vixen Telescope PORTA II-ED80Sf Description

Slow-motion handles

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.
Dovetail-plate attachment

With Vixen's renowned dovetail-plate system, many optical tubes, up to 160mm in outer diameter, can easily be swapped on and off the mount.
Accessory tray

An accessory tray holds small pieces such as a camera or eyepieces. Very useful when observing at night.
Compartment for tools

Slow-motion handles positions and the amount of friction on the axes are adjusted with tools located in the compartment under the rubber covering. You will always have your tools available.
Detachable tripod system

The mount head and tripod are detachable by single fixing bolt which makes it convenient for transport and storage.
Friction control system

The optical tube can be moved freely by hand and the friction holds its position where you stop it. It allows you to manually point the telescope at target celestial objects you wish to view.

All-optical tube units with PORTA II alt-azimuth mount is equipped with a finder scope to facilitate pointing the celestial object.
