Vixen NA140SSf 140mm Refractor Telescope with GPD2 Equatorial Mount, HAL130 Tripod, STAR BOOK-S GPD2-NA140SSf-SBS 26263 Telescopes Product Info

The Vixen NA140SSf 140mm Refractor Telescope with GPD2 Equatorial Mount, HAL130 Tripod, STAR BOOK-S GPD2-NA140SSf-SBS 26263 is a 5.5 inch Vixen Telescope with incredible performance. This 140mm NA (Neo-Achromatic) Refractor Telescope by Vixen features a two element secondary lens at the rear of theimage 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. The included GPD2 Equatorial Mount is the stronger and heftier of the GP mounts. With its solid steel R. A. and Declination axes and brass worm gears this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography the worm gears are machined to a very high precision that minimizes periodic error. Also included is the Vixen Starbook S with built-in starchart for complete Go-To capabilities. The Vixen GPD2 Mount holds almost 50% more weight than the GP2 and comes standard with tripod and counterweight. It is easy to use and functions well for both the visual observer and astrophotography. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0° to 62° in altitude. With these features of the Vixen NA140SSf Refractor Telescope, Deep Sky objects are easily visible and Astro-Imagers looking for a fast instrument with clear aperture will be highly impressed.
