Vixen Optics- Telescope and Mount Packages -NA140SSf with Sphinx SXD Mount


Vixen NA140SSf with Sphinx SXD Mount (Item #95869)

The NA 140Ssf(Neo-Achromatic) refractor features a two element secondary lens at the rear of the optical tube to provide a flatter field of view (Petzval design). Spherical abberation and field curvature are less than 1/3 to 1/5 of standard doublet refractors.

The SPHINX SXD equatorial mount and STARBOOK controller have been engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built in motors and the world's first star chart go-to controller, STARBOOK, with a large full color LCD display. The STARBOOK is easy to use and makes the SPHINX available to a wide range of ages and experience levels. A large astronomical database with 22,725 celestial objects is stored. A LAN Port within the controller allows for computer control and network connectivity.
