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. 
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. Manufactured in Japan. Includes Vixen's new Dual Speed Focuser.  Instruction Manual here.
