Vixen NA140SSf, 140mm, 5.5" Neo Achromatic Refractor Optical Tube with Atlux Mount and P70 Pillar

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 new Atlux mount.

The Atlux is a mid-sized Go-To Equatorial mount newly desgined to work with the STAR BOOK hand controller. The revolutionary STAR BOOK system features sky charts, PEC and autoguider functions. With its 75 pound load capacity this mount is a solid platform for both the astrophotographer and visual observer.
