Vixen A70LF f/12.9 Doublet Refracting Telescope and Mobile Porta Mount

This Vixen 70 mm Refractor Telescope sits atop their Mobile Porta Mount.

The Mobile Porta Mount is a variation of Vixen's award winning Porta II Mount. This mount is easier to transport due to its unique multi-function fork arm which allows the Mobile Porta to fold much more compactly than its predecessors. At less than 8 pounds this mount is ready to go to all your observing sites.

The 70 mm (2.76-Inch) Aperture Doublet Telescope can be moved manually to the right position and then fine tuned with the slow motion controls. The multi-function single fork arm folds without the use of tools for easy transport and storage. Setting up your scope in minutes is a simple operation.

The direction of the multi-arm can be rotated at 15 degree intervals to avoid having the telescope impeded by the slow motion controls. Additionally, the vertical slow motion control can move outward. The Mobile Porta features a friction stop system and a removable mount head.
