Explore Scientific ED80 80mm f/6 (480mm) Air Spaced Carbon Fiber Triplet Refractor Telescope 1.45 arcsec Resolution 2-Speed Focuser -

The Explore Scientific ED80 Carbon Fiber Refractor Telescope combines high-end optics and well-executed design to create an exceptional instrument for everything from deep sky observation to comet-chasing to astrophotography. With its 80mm triplet objective lens, the refracting telescope uses true diffraction-limited, apochromatic optics to open up the skies revealing wonders like the magnificent desolation of the lunar terrain or the vibrant nature of Saturn with its swirling storms and serene ring system structure.
The lens is air-spaced with a middle element made of genuine HOYA FCD1 extra-low dispersion glass and all air-to-glass surfaces have been multi-coated with proprietary EMD (Enhanced Multi-layered Deposition) coating. All of these features collide to produce stunning high contrast images with crisp definition that encourage viewers to explore the celestial secrets of a broad range of subjects, including the deep sky treasures of the entire Messier and Herschel catalogues.
The quality of the optics also allows those seeking to push magnification based on their choices of eyepieces or focal extenders to do so without sacrificing clarity. The emphasis on precision continues outside of the lens construction with the addition of a three-point collimation cell that allows for pinpoint adjustments of the objective lens. The two-inch focuser has two-speed control and multiple set screws are in place to lock all elements.
Sized to fit a vast range of eyepieces, the included diagonal has a precision-polished, two-inch mirror that is 99% reflective to transmit even more light. The tube that connects the diagonal to the scope itself is also tapered for added security should one of the set screws be accidentally loosened. Beyond the optics, the ED80 can list its carbon fiber housing among its many assets. In addition to being lightweight, the material prevents unintended focus changes from the tube shrinking or expanding due to temperature fluctuations, which can be crucial to maintaining a continuous clear image during a long night of astrophotography or observation.
The scope also has a retractable dew shield that prevents moisture from building up on the lens and eliminates the image interference caused by stray light. A bracket for a finder scope is also mounted on the tube. For added versatility, the telescope comes with two extension tubes, has a vixen-style mounting plate and is equipped to fit both European- and American-style tripod threads. Explore Scientific standing in the grab-and-go class of observation tools, the telescope comes in a deluxe storage case with a clamping lock system and a molded foam interior that protects the device and its accessories. All in all, the ED80 maximizes its exceptional optic elements and high design standards to create such brilliant images.

Lining and Layers:

  • Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter


  • The tube assembly of the ED80 Triplet is made of lightweight, yet strong carbon fiber


  • The contrast on the Explore ED80 is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly
  • This telescope has true APO, or apochromatic, optics
  • Diffraction limited at .25PV or better
