Vixen Optics 39977 overview

  • 1Description

Vixen Optics gives you a complete astronomical platform ideally suited for beginners or as a simple grab-and-go option for more experienced observers by putting together their Advanced Polaris-M Mount with A80MF Telescope.

  • A80MF 80mm f/11.4 Achro Refractor Telescope (OTA Only)

    Vixen Optics' A80MF 80mm f/11.4 Achro Refractor Telescope is designed with an achromatic lens system that produces bright and clear high-contrast images with true color representation across its entire distortion-free field of view. Its 80mm objective gathers more light than smaller-objective models while still being easy to handle and transport - especially when you have to carry it a distance to your observation area. This lens system, coupled with the fully-coated optics, will give you great views of the Moon, planets, planetary moons, and brighter deep sky objects. You will be able to split binary stars and observe bright objects with virtually no comas. The A80MF is offered here without a mount or tripod, but the scope does comes with two eyepieces, and a 90° erect-image prism that will be ideal for both astronomical and terrestrial use.

  • Advanced Polaris-M Motorized EQ Mount with SB One and Tripod

    Vixen's Advanced Polaris-M Motorized EQ Mount is an upgrade from the basic AP mount with the addition of a Right Ascension motor module and the Star Book One hand controller. The micro-stepper motor's full-circle brass wheel gear allows the mount to track over extremely long periods with little error for long-exposure astrophotography or prolonged observation of a single celestial object. While this mount configuration does not have full Go-To capabilities, once you Polar align the mount and manually navigate to your subject, the Star Book One controller will track it across the right ascension all night. This version of the AP-M includes Vixen's TL130 adjustable-height tripod.

    Use the included Star Book One hand controller to move the scope for navigating and to track celestial objects. Since near and deep sky objects appear to move at different speeds, the controller features celestial, solar, lunar, and King's rate tracking speeds, in addition to slew speeds from 0.05x to 1000x. An integrated autoguider port adds to the mount's usability.
