The NA (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.

Pair this optical tube with the SPHINX equatorial mount. The STARBOOK controller have been intelligently 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 Sphinx’s design is exceptional and the exterior styling is equally attractive.
