An ideal telescope for grab and go observing

The A70Lf refractor telescope is designed to provide a comprehensive viewing experience for beginners, offering captivating perspectives of lunar craters and Saturn's rings.


Simple and intuitive operation by friction stop motion

The MOBILE PORTA shares similar functionalities with the PORTA II, allowing users to manually adjust the telescope in both vertical and horizontal directions with ease. The telescope can be freely swung and brought to a halt using straightforward friction mechanisms.


Dovetail-plate Attachment

Utilizing Vixen's renowned dovetail-plate system, this mount facilitates the effortless attachment of various optical tubes. Capable of accommodating optical tubes with a weight of up to 3.5 kg, it provides a versatile and adaptable platform for astronomy enthusiasts.


Accessory Tray

The accessory tray serves as a practical solution for organizing small items like eyepieces, offering convenience during nighttime observations.


Slow motion control handles

The MOBILE PORTA features slow-motion control handles that enable precise control over the entire range of vertical and horizontal movements. This functionality proves particularly beneficial when observing at high magnifications, especially when paired with the friction stop mechanism. Additionally, users have the flexibility to adjust the position of the slow-motion control handles as required for optimal maneuverability.


Movable multi-arm

The multi-arm's orientation can be adjusted in 15-degree intervals, allowing users to prevent any interference with the slow-motion control handle or optical tube. Plus, the vertical slow-motion control handle can be extended horizontally to prevent any potential conflict with the horizontal slow-motion control handle. This flexibility enhances the user experience by offering customizable configurations to avoid operational hindrances.


Foldable mount head

The mount head of the MOBILE PORTA is designed with the capability to be folded, providing a convenient solution for storage and transportation. Additionally, the mount head is detachable from the tripod, further facilitating ease of handling and portability.
