Vixen ED103S Refractor Telescope with GPD2 Equatorial Mount and StarBook S Controller
Written by Buy Telescopes Online on September 24, 2008
The Vixen ED103S is an apochromatic refractor with fantastic contrast and a 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 quoted in the 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 bring in enormous quantities of light but simply cannot compare to the contrast of the apochromatic refractor.The included flip-mirror adapter allows either 90° or straight-through observing. With an eyepiece upon 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 GPD2 equatorial mount is the stronger and heftier of the GP mounts. With it’s 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. Add the new Vixen Starbook S with built in starchart for complete Go-To capabilities. 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.

TeleVue 102i Package w/ Bino Vue
Written by Buy Telescopes Online on September 24, 2008
Tele Vue-102i Package Includes - Hard Case - 1.25 Everbrite Diagonal - 1.25 Adapter - Ring Mount - Bino Vue.Our newest model APO refractor (102mm aperture 880mm focal length f/8.6) is designed to permit lower-power wider-field binocular viewing - all in a more compact form. The Tele Vue-102i sports the same overall length as the Tele Vue NP-101 making it easier to transport. It will fit in the NP-101’s soft carry bag. By having a tube that’s five inches shorter than the regular Tele Vue-102 model it is now possible to use the Bino Vue without its standard 2x amplifier/corrector. The complete version of the Tele Vue-102i includes a Bino Vue body with a specially designed 1x prism compensator for correcting the slight aberrations introduced by a prism. The 2x amplifier is not included as the new tube’s five-inch shorter path length no longer requires it. Current Bino Vue owners can purchase the OTA (Optical Tube Assembly) version of the Tele Vue-102i (product code WBO-4086) which includes the hard case 1x prism compensator and flat-top adapter. For Solar viewing in Hydrogen-alpha with Coronado filters up to 90mm the Tele Vue-102i will permit full solar disc Bino Vue operation since the maximum field is approximately 1.75 inches. For terrestrial viewing (upright but reversed image) the new comfortable 60-in. Everbrite mirror diagonal is sturdy enough to support and lock the Bino Vue with prism compensator attached. The Tele Vue-102i can also be used without a Bino Vue by combining both the two-inch and three-inch extension tubes between the focuser and the diagonal. The telescope then functions exactly like a regular Tele Vue-102.

With the Tele Vue-102 we offer the amateur a simpler less expensive four-inch refractor which retains Tele Vue’s core values: outstanding optical performance and superb mechanical quality. The new Tele Vue-102 is a 4-inch 2-element f/8.6 APO air-spaced doublet similar to the appearance to the 4-element f/5.4 Tele Vue-101 but 5 inches longer. The Tele Vue-102 achieves similar diffraction-limited high-power APO viewing as its 4-inch sibling along with a wide 3-degree maximum visual field (compared to 4.9 degrees for the Tele Vue-101). A dedicated 0.8x reducer/flattener is available to permit great astrophotography of star fields at f/6.9 with the Tele Vue-102. The Tele Vue-102 is offered as a complete package or as an O.T.A. since you may already own a 2-inch diagonal and adapter as well as an eyepiece collection and mounting rings. These items are available expertly for the O.T.A. I hope you agree that the 4-inch Tele Vue-102 offers the high standard of performance and features of Tele Vue refractors along with a unique value.

The TeleVue 85’s mix of aperture and small physical size makes it a wonderful “go anywhere do anything” crossover instrument with TeleVue quality of course. With APO performance and airline portability the TeleVue 85 has been delighting astronomy and birding enthusiasts and reviewers alike. “Eye-popping performance that raises the standard of excellence for highly portable instruments.” Evaluation of double-stars lunar detail deep sky and photography were reported in Sky and Telescope as “Truly awesome! …Incredible!…the view almost blew me off my chair!…” The conclusion: “…an extremely powerful compact instrument capable of delivering stunning images of the universe.” The Better View Desired website reviewer summed up the TeleVue “experience” when he said he would choose the TeleVue 85 “…to really enjoy the incredible beauty of the living birds… And even now every time I look at a bird through one of the exceptional conventional spotting scopes I’ll be thinking: ‘I wonder what this would look like through the TeleVue 85? I wonder what this bird really looks like?’” Yes pure enjoyment of nature’s beauty without awareness of a thing in between.
