The New Mobile
Porta 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.
Your 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 an of of 15 degree intervals
so that you avoid having the telescope impeded by the slow motion handles.
Additionally, the vertical slow motion control can move outward.
The Mobile Porta includes all the features of the original Porta II mount such
as slow motion handles, friction stop system and removable mount head.The Vixen A62SS features a compact 62mm f8.4 (520mm focal length) fully multi-coated 4-element objective lens. The optical tube is only 305mm long when the dew shield is retracted. This makes for one great grab and go telescope.
The Vixen A62SS comes with an aluminum tube and dew shield that is finished in Vixen astronomical white. The dew shield retracts reducing the length of the telescope from 370mm to 305mm making for easy storage. Extending the dew-shield minimizes dewing of the objective lens at night and works as a glare shade during the daytime.
The Objective lens: D=62mm F=520mm (f/8.4) consists of 4 Achromatic lens that are multicoated and configured perfectly to give this optical tube the best combination of compactness, contrast and resolution. The Vixen A62SS includes a precision Crayford Focuser with a compression ring eyepiece adapter. The extension tube adapter is threaded in 42mm diameter for a T-ring and 37mm for commercial available filters. A scale is engraved on the drawtube. The telescope includes a rotatable focuser. This is useful when doing astro-photography for camera positioning and helpful to look through a finder scope in a convenient position when you use the scope with a variety of mounts. It also comes with a built-in dovetail attachment plate. The base of the dovetail attachment plate has a 1/4 inch thread socket (changeable to 3/8 inch thread socket). This allows the telescope to be attached to either an astronomical mount or standard camera tripod.
The Vixen A62SS features a side face flat lock on the finder bracket shoe that prevents a finder bracket from marring the optical tube. It also comes with a custom designed soft padded case to protect the optical tube and includes additional cutouts for a variety of accessories.
