Explore ED80 Air-Spaced Triplet Refractor Highlights…

  • The tube assembly of the ED80 Triplet is made of lightweight, yet strong carbon fiber
  • This telescope has true APO, or apochromatic, optics
  • Diffraction limited at .25PV or better
  • Genuine ED glass from Hoya Japan
  • Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter.
  • The contrast on the Explore ED80 is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly
  • While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. This means that while you can send your ED80 to the Explore factory for collimation, it is not required.
  • The ED80 APO Triplet comes with a heavy-duty 2" dual-speed rotatable focuser, included 2 draw tube extensions.
  • Included 2" diagonal has a precision-polished mirror with enhanced 99% dielectric coatings. A 1.25" compression ring adapter is part of this package.
  • To attach your Explore Scientific ED80 Air-Spaced Triplet telescope to a variety of mounts, we have included the "Vixen-style" dovetail. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
  • All Explore Scientific products come with a STAR Extended-Life-of-the-Product Warranty. Upon registration, this product will be under warranty for as long as it is manufactured, plus five years.

 This 80mm f/6 ED Apochromatic triplet is an air-spaced triplet refractor telescope for observing and photography of celestial objects. Instrument utilizing Hoya ED glass, comes equipped with a 99% dielectric-coated 2-inch diagonal, Finder Scope and TwiLight I Mount available separately.



The Critical Element: Optics

Explore Scientific uses ED (Extra-low Dispersion) FCD1 (Dense Fluor Crown) glass developed and manufactured by Hoya Optical of Japan. Using the right glass with the appropriate properties enables the production of lenses that offer superior sharpness and color correction.

The optics used in Explore Scientific ED Air-Spaced Triplet refractors are truly diffraction-limited at .25PV or better. As a privilege of ownership, those who wish to obtain a copy of their interferometric data can request it up to 90 days after registration of their ED Triplet telescope by contacting the Explore Scientific Customer Service Department.



 2" 99% Reflective Dielectric-Coated Diagonal

The purpose of a diagonal is to securely hold your eyepiece and to give you a comfortable viewing angle.

Provided as standard equipment, Explore Scientific's 2", 99% Reflective, Dielectric-Coated Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment.





EMD Coatings

EMD (Enhanced Multi-layer Deposition) Coatings eliminates light scatter and maintains high image contrast. This proprietary coating is applied to all Explore Scientific lenses in multiple layers for added durability.

Contrast is further enhanced by the installation of multiple baffles in the optical tube that mask and deflect unwanted stray light.
