Orion ED80T Carbon Fiber ED APO Refractor Telescope

The ED80T 80 mm (3.15-inch) aperture, CF Triplet Apochromatic Refractor Telescope by Orion:

Orion is proud to announce an exciting addition to our already prestigious line of ED refractors, the 80 mm apochromatic triplet Orion ED80T CF. With an 80 mm (3.15-inch) aperture triplet objective featuring FPL-53 extra-low dispersion glass, views come through true to color and exhibit tack-sharp resolution. 

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 480 mm (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-inch with the dew shield fully retracted. The telescope measures 18.25-inch long 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 5.5-pounds, 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 (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-inch/20 accepter. 

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 home-in on just the right focal point. The included 2-inch to 1.25-inch eyepiece adapter allows trouble-free use of higher magnification 1.25-inch telescope 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.

  • orion ed80t needs a field flattener?

    The ED80T does not require a field flattener to use. We do recommend getting the field flattener if you are going to use this telescope for astrophotography: https://www.optcorp.com/or-8893-field-flattener-for-short-refractors.html

  • Hello. what is the condition of the telescope, was it a demo? Does it have a warranty? I am very interested thank you.

    Albert, The condition of the refractor is brand new with the full warranty. We have it as a clearance item. please give me a call at 800-483-6287.

  • What accessories would be needed to attach a Canon DSLR to the 'scope?

    You would need to have at the very least a 50mm extension tube (OS-E250), a 2" T2 adapter (OS-A2T), and a Canon T ring (CE-93419). This will result in a curved field, though (stars not in focus in the corners when focused in the center), so replacing the
