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.
