VIXEN A70Lf 70mm f13 Mobile Porta Mount Achro Refractor AZ Telescope

Ideal for casual watching the skies or the ground, the Vixen Optics A70Lf 70mm f/13 Achro Refractor AZ Telescope with Mobile Porta Mount combines a competent optical tube assembly with a highly portable mount and an array of accessories to give you all you need to get out and start observing right away.

An ideal telescope for grab and go observing.

The A70Lf refractor is a basic all-around telescope that gives beginners intriguing views of lunar creaters and Saturn’s rings.

“The glass is well coated and good quality.

The views are sharp with little false color on objects like the Moon. Saturn was sharp & you can make out the rings and one of its moons. Excellent performance and it is worth the price.

Vixen makes a great scope and this scope would make a great first scope for the beginner or additional scope for the serious Amateur Astronomer.”

The 70mm telescope features a refractor-style light path with an achromatic lens design to transmit accurate colors without fringing or distortion at the edges. Anti-reflection multi-coatings further improve color while boosting contrast and clarity. Two eyepieces offer low and high magnifications, the included Barlow lens doubles the power of each eyepiece to give you four magnifications using just two oculars. A 90° erect-image diagonal corrects the view to allow comfortable use on terrestrial subjects so you can use the telescope as a conventional spotting scope.

Supporting the telescope is Vixen’s Mobile Porta mount with an adjustable-height aluminum tripod. Designed for portability and ease-of-use, this manual alt-azimuth mount has a friction control system that allows you to move it by hand without the need to fumble with clutches or locks, and stays in place when you release it. Dual axis slow motion handles let you fine-tune the scope placement once you get close to your subject. The two-stage tripod adjusts from 28-51″ to accommodate a wide variety of users and viewing positions.

Vixen Telescope MOBILE PORTA A70Lf Description

  • Simple and intuitive operation by friction stop motion.

    The MOBILE PORTA has the same function as the PORTA II and you can swing the telescope by hand in the vertical and horizontal directions freely and stop with simple friction.

  • Dovetail-plate Attachment

    With Vixen’s renowned dovetail-plate system, different optical tubes can be easily attached. The mount holds optical tubes weighing up to 3.5 kg.

  • Accessory tray

    The accessory tray is convenient in putting small pieces such as eyepieces. It is useful when observing at night.

  • Slow motion control handles

    The slow motion control handles of the MOBILE PORTA allow for operating the mount in the whole-circle of the vertical and horizontal movements. It is helpful as used together with the friction stop mechanism when observing at high magnification. The position of the slow motion control handles can be changed if needed.

  • Movable multi-arm

    The direction of the multi-arm can be rotated in 15 degree intervals so that you can avoid interfering with the slow motion control handle or the optical tube. In addition, the vertical slow motion control handle can be moved outward, in the horizontal direction, to avoid interference with the horizontal slow motion control handle.

  • Foldable mount head

    The mount head of the MOBILE PORTA can be folded for convenient strage or transport. The mount head is detachable from the tripod. The tube and Tripod Bag 100, sold separately, is the perfect bag for storage and transport of your MOBILE PORTA. An optical tube cannot be put together in the bag.
