Model: VX39905
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 storage 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.
