Vixen 140mm NA140SSf Neo Achromat Telescope with Sphinx SXW Equatorial Mount

 


Now with the 2 Speed focuser,  flip mirror , 7x50 FinderScope and Tube Rings complete

The NA140S (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 aberration and field curvature are less than 1/3 to 1/5 of standard doublet refractors.

Weighing in at 14.3 lbs this 5.5 inch Vixen telescope is an incredible performer. Deep Sky objects are easily visible and Astro-Imagers looking for a fast instrument with clear aperture will be impressed with the NA140’s performance. The advanced 4-element objective lens, set in two groups, minimizes residual chromatic aberrations. With its unique Petzval like correcting lens at the rear, this Neo-Achromatic refractor telescope is specifically designed to provide improved color and a flat field, ideal for astrophotography. Manufactured in Japan. Includes Vixen's new Dual Speed Focuser.

 

One user states:

“Correction is so good, that I have also used the telescope for stellar and lunar photography - a use for which I had not originally purchased this telescope.” The NA140 “has excellent imagery across the field of the Canon DSLR but seems to have little or no apparent lateral color error. Its low weight for its aperture, easy portability and excellent medium focal length and fast f-ratio make it the perfect 'one telescope does it all’ product.

 

Vixen Sphinx SXW Mount

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.

Vixen's Sphinx SXW Equatorial Mount features leading edge innovations developed through decades of experience in building German Equatorial Mounts. The Vixen SPHINX SXW mount and STAR BOOK hand controller are groundbreaking advancements in high speed, portable GoTo mount technology.
