  • Description

    The Vixen 39982 consists of an 80 mm f/7.5 ED refractor and the Advanced Polaris-M Equatorial Mount and Tripod. This is a great entry or intermediate level telescope package that can grow as your enjoyment of the hobby of astronomy does! The AP-M mount comes with an RA motor and Star Book One hand controller, giving you motorized tracking of objects as they move horizontally across the sky. You can also add a Declination motor module whenever you like—the Star Book One is capable of controlling both. And since it is super easy to attach and remove the optical tube assembly, you can add a different style telescope when you want to change it up a bit. In the meantime, enjoy views of hundreds of celestial objects with this quality telescope, and have fun using this very smooth, well made equatorial mount!

    About the ED80SF Refractor Telescope

    The Vixen ED80Sf refractor telescope features high-grade extra-low dispersion glass with multi-coated optics for crisp, clear views. Its “just right” focal ratio of f/7.5 produces sharp, color-free high contrast images. At only 22.4", this is Vixen’s ultimate grab-n-go APO travel scope. The ED80Sf telescope comes complete with an aluminum Case, flip mirror, finder scope and rings.

    About the Vixen Advanced Polaris M Mount

    The Vixen Advanced Polaris-M is an easy to use German equatorial mount that is designed to be easily transformed into a variety of configurations. This classic equatorial mount includes the RA Motor module, STAR BOOK ONE hand controller and an adjustable tripod.

    The STAR BOOK ONE Controller is a dual axis handheld controller. The 4 buttons on the controller move the mount electrically in the X and Y axis (RA and, if you buy the Dec Motor Module, in DEC). The controller includes a built-in red LED light for illumination to avoid loosing night vision. Versatile tracking options are available; sidereal rate, King Rate, lunar rate, and solar rate. Different tracking speeds are available for time lapse photography. The controller works in both the northern and southern hemispheres. Backlash compensation provides reduced time lag at the point of reverse motion and the controller can be used for auto guiding with an auto guider compatible with SBIG auto guiders. PEC rectifies irregular motion of the tracking gear wheels that affect long exposure astrophotography.

    The Advanced Polaris-M German Equatorial Mount is ideally suited for both beginners and experienced observers who want simple equatorial mount with a easy-to-control right ascension drive. To add dual-axis drive functionality to this mount, we recommend adding the DEC Motor Module, which is sold separately.

    The Vixen Advanced Polaris-M Mount securely supports the ED80Sf telescope for comfortable night sky observing. The mount can be quickly moved to your target object in right ascension via the Star Book One controller, or manually in either RA or Declination, and has slow motion controls on both RA and Dec that allow for smooth manual movements once your choice of object is in the field of view. A wide selection of accessories and modules (including a DEC Motor Module) are available to customize the Advanced Polaris mount further. This EQ mount also comes with the Vixen AL130 Tripod and a 2.2 pound counterweight.
