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 designed to work with the STAR BOOK hand controller. The revolutionary STAR BOOK system features sky charts PEC and auto guider functions. With its 75 pound load capacity this mount is a solid platform for both the astrophotographer and visual observer.Specifications:NA140SSf:Focal Length: 800MM (f5.7)Tube Weight: 14.3 lbsFinder Scope: 7x50 field of view 7 degreesAtlux Mount:Polar Axis Scope: 6x20mm wide 8 degree field of viewGo-To System:STARBOOK SystemMaximum loading weight: 75 lbsCounterweight: 3.5 kg and 7 kgWeight: 43.4 lbs w/o counterweight

The newly designed high definition ED lens on the ED115S gives excellent performance with a short optical tube for easy handling. The new ED lenses feature brighter images from the shorter f/7.7 focal ratio to capture crisp pinpoint star images for your enjoyment. The new ED115S lenses are made with environmently friendly technologies free of hazardous lead that helps to support a cleaner global environment.The optical tube comes equipped with a metal carry handle for easy one-hand carrying.Sphinx SXD Mount Features:Solid Steel RA and DEX Axis shaftsNeedle Bearings180 Tooth Brass Worm Gear in both axesInteractive Starbook with a 4.7 Color LCD Display - scrolls and zoom into detailed star charts with a built in speakerMount Capacity 50 lbs.Includes one 4.2 lb and one 8.2 lb counterweightWeight: 8.8 kg/ 19.4 lbsFull Go-To capabilities to over 22000 objectsUniversal GP Plate receiver allows many telescopes to mountCompletely upgradeable firmware and comet database

The new lenses of the ED103S focus the full spectrum of visible light to a critical point much more accurately than past ED product. The ED103S lenses are almost free of chromatic aberration in all colors and are critically sharp edge to edge. The astro-photographer will be especially pleased with the high contrast images through this telescope. The ED103S comes complete with 7x50mm finder finder bracket 2

The Vixen ED103S is an apochromatic refractor which has fantastic contrast and 4 aperture sufficient for viewing most of the planets and many stars. With its ED glass elements chromatic aberration has been reduced to nearly undetectable levels permitting a much more practical use of the higher magnifications than when using other achromatic refractors of seemingly identical specifications.Vixen's ED Glass has brought refractors back to the forefront of premium telescope choices to compete with the 8 and larger ubiquitous Schmidt-Cassegrains that while bringing in enormous quantities of light simply cannot compare to the contrast of the apochromatic refractor.The included flip-mirror adapter allows either 90 degrees or straight-through observing. With an eyepiece on each end of the flip-mirror you can quickly switch between the two as the declination of your object of interest changes its location in the sky.The SPHINX equatorial mount and STARBOOK controller have been intelligently engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built-in motors and the world's first star chart go-to controller STARBOOK with a large full color LCD display. The Sphinx's design is exceptional and the exterior styling is equally attractive.

The ED115S lenses are made with environment-friendly technologies free of hazardous lead that helps to support a cleaner global environment.The optical tube comes equipped with a metal carry handle for easy one-hand carrying.The 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 especially machined to a very high precision that minimizes periodic error.The GPD2 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-degrees to 62-degrees in altitude.GPD2 Mount Features:R.A Axis: 144-tooth worm gearsDeclination Axis: 144-tooth worm gearsR.A. graduations: RA 10 min. incrementDec graduations: 2-deg. incrementsPolar Axis Scope: 6 x 20 wide fieldMount includes pre-installed variable intensity illuminatorPolar Axis Altitude adjustm

When The ED81S was introduced it set a new standard for 80mm APO Refractors. The combination of better color correction from the new ED glass and brighter images from its fast f/7.7 focal ratio will satisfy the most demanding visual astronomer or astro-photographer. The new ED glass produces clear and high contrast viewing virtually free of false color. The design uses newly developed environmentally friendly glass technolgy. The optical tube is very stable yet light weight. The top carry handle also includes a 1/2-20 stud for piggyback camera mounting. The supplied flip mirror system is threaded for two-inch filters.The Sphinx SXD incorporates one piece hardened steel RA and DEC shafts with needle bearings throughout the new Sphinx D can handle a load capacity up to 50 lbs. The Sphinx D comes complete with PEC and the incredibly accurate SX Polar Finder Scope. The STAR BOOK controller provides you with built in star charts upgradeable data base and full color images.
