VIXEN NeoAchro 140SS Refractor Telescope Weighing in at 14.3 lbs this 5.5 inch Vixen telescope is an incredible performer and assures you of clear deep sky views. Deep Sky objects are easily visible and Astro-Imagers looking for a fast instrument with clear aperture will be impressed with the NA140SS Telescope' s performance. The advanced 2-element objective lens, behind the primary objective lens, gives bright images with excellent color correction. This minimizes residual chromatic aberrations for edge to edge sharpness and results in star images to less than 60 microns in size at the edge of the field of view. This new NA140SS Telescope has all Japanese made glass optics. 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. This is evident in the images by Dan Llewllyn below. Manufactured in Japan. 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.” NA140SS Telescope Specifications: Optical Design Neo Achromat Refractor 2 Group 4 Element Design Aperture 140mm Focal Length 800mm Focal Ratio f/ 5.7 Coating Multi Coating Resolving Power 0.82 arc sec Limiting Magnitude 12.5 Light Gathering Power 400x Finder Scope Optional Focuser Dual Speed Adapter Thread 60mm Astrophotography Prime Focus & Eyepiece Projectio Visual Back Compression Ring Optical Tube Length 41” ( 1040mm) Optical Tube Diameter 5.5” ( 140mm) Optical Tube Weight 14.75 lb Available Accessories 7x50mm Finder Scope; Flip Mirror Diagonal; Dovetail Plate
