Orion ED80T CF Apochromatic Refractor
- Fabulous triplet apo refractor performance - we feel this is as false-color-free as a refractor can be!
- 80mm, f/6.0 design - great for wide-field visual or imaging use
- Carbon-fiber construction - strong, light, thermally stable and darn good looking!
- Robust dual-speed focuser - once you use this focuser you'll never want to use a single-speed again!
- finderscope bracket, dual dovetail/photo tripod adapter mounting block - for guided imaging or wide-field altazimuth star hopping
- A perfect grab-n-go visual instrument AND an exceptional wide field astrograph
Apochromatic refractor telescopes have a devoted following amongst amateur astronomers, and for good reason. The crisp view offered by a high-quality apo refractor is truly a wonder to behold and share. Apochromatic refractors 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 apo refractors have helped to make them instruments of choice by many real-time observers and imaging experts alike.
The ED80T CF 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 ED optics virtually eliminate chromatic aberrations making the ED80T CF an excellent candidate for astrophotography use when used with an imaging-capable EQ mount and CCD or DSLR camera. The relatively small size and light weight of the 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-inches with the dew shield fully retracted. The telescope measures 18.25-inches when the dew shield is fully extended to minimize peripheral glare and dew accumulation.
The striking carbon-fiber tube is nifty to look at, and makes the ED80T CF a lightweight luxury to transport and mount. Weighing in at a mere 6.0 lbs. including the diagonal, this is one 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 EQ mount equipped with a narrow, or "Vixen-style," dovetail saddle without the need for additional mounting accessories. While a stable motorized equatorial (EQ) mount is recommended for astrophotographic pursuits, the ED80T CF 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. Adding an optional correct-image 45-degree diagonal would provide you with a daytime telescope worthy of virtually any landscape or wildlife viewing exploit.
In keeping with Orion's established tradition of offering quality products at affordable prices, the ED80T CF is offered to you at an amazing value. What's more, we've included top-notch features and accessories which are sure to please even the most discerning apo aficionado. The precision machined Crayford-style 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 hone-in on just the right focal point. A 2-inch mirror diagonal with dielectric coatings provides a comfortable nighttime view orientation and optimizes reflectivity, ensuring as many of those lovely photons as possible reach the focal plane. The included 2-inch-to-1.25-inch eyepiece adapter allows trouble-free use of higher magnification 1.25-inch eyepieces or 1.25-inch accessories. For storage and safe transport, everything fits nicely in the included hard case with custom die-cut foam interior.
