About the Orion ED80T CF Triplet Apochromatic Refractor Telescope...
Here''s one of our staff favorite Orion Telescopes that is especially popular with astrophotography enthusiasts, the Orion ED80T CF Triplet Apochromatic Refractor Telescope. With an 80mm aperture triplet objective featuring FPL-53 extra-low dispersion glass, views and captured images come through true to color and exhibit tack-sharp resolution.
Apochromatic refractor Orion Telescopes have a devoted following amongst amateur astronomers, for good reason. The crisp view offered by a high-quality apo refractor is truly a wonder to behold and share. Apochromatic refractors, like the Orion ED80T CF Triplet Apochromatic Refractor Telescope, significantly reduce chromatic aberration, or false color, compared to standard achromatic refractor telescopes due to the use of "ED" (Extra-low Dispersion) optical glass and use of three optical elements. The visual and imaging benefits of apochromatic refractor Orion Telescopes have helped to make them instruments of choice preferred by many real-time observers and imaging experts alike. Combine with a Orion Telescope Mount for excellence in astrophotography.
The Orion ED80T CF Triplet Apochromatic Refractor Telescope is a versatile power performer telescope well-suited for multiple applications. With a focal length of 480mm (f/6.0), its fast unobstructed optics yield detail-rich visual views of solar system and wide-field deep-sky objects alike. The triplet objective and top-notch ED optics virtually eliminate chromatic aberrations making the ED80T CF Orion Telescope an excellent candidate for astrophotography use when used with an imaging-capable equatorial mount and Orion CCD Cameras or DSLR camera. The relatively small size and light weight of the refractor telescope makes it perfectly portable for escapades to dark-sky locations for either visual or photographic expeditions. The retractable dew shield makes the ED80T CF even more compact for storage and transport, with a length of 14.3" with the dew shield fully retracted. The Orion Telescope measures 18.25" long when the dew shield is fully extended to minimize peripheral glare and dew accumulation.
The striking carbon-fiber Orion Telescope refractor tube is nifty to look at, and makes the Orion ED80T CF Triplet Apochromatic Refractor Telescope a lightweight luxury to transport and mount. Weighing in at a mere 5.5 lbs., this is one Orion Telescope you won''t have to break your back (or bank account) when considering mounting options. The integrated dovetail mounting base attaches directly to any Orion equatorial (EQ) mount equipped with a narrow, or "Vixen-style," dovetail saddle without the need for additional mounting accessories. While a stable motorized EQ Orion Telescope Mount is recommended for astrophotographic pursuits, the ED80T CF refractor Orion Telescope can be adequately mounted on a wide variety of lightweight sturdy field and photo tripods by virtue of the same integrated dovetail mounting base which features a threaded 1/4"-20 acceptor.
In keeping with Orion''s established tradition of offering quality astronomy products at affordable prices, the Orion ED80T CF Triplet Apochromatic Refractor Telescope is offered to you at an amazing value. What''s more, we''ve included top-notch features and Orion Telescope Accessories which are sure to please even the most discerning apo aficionado. The precision machined Crayford-style telescope focuser provides dual-speed focus adjustment perfect for dialing in delicate details of celestial and terrestrial subjects. The smaller fine focus knob adjusts focus at a rate of 11:1 compared to the coarse focus knob, giving you the ability to home-in on just the right focal point for sharp performance and crystal-clear observations and astrophotos. The included 2" to 1.25" eyepiece adapter allows trouble-free use of higher magnification 1.25" telescope eyepieces or 1.25" imaging cameras and other Orion Telescope Accessories. For storage and safe transport, everything fits nicely in the included hard case with custom die-cut foam interior.
