Explore Scientific ED80 Essential Edition Telescope

The Explore Scientific ED80 Triplet APO Essential Edition is a value oriented member of the 80mm apochromatic refractor class, priced only slightly higher than competing doublet refractors.

The faster f/6 optics of this triplet design offer advantages in terms of both physical size and the potential field of view for users. In fact, when coupled to the right eyepiece or camera the 480mm focal length of this instrument will yield a five-degree field of view.

About Explore Scientific Air-Spaced Triplet Apochromatic Refractors

When the designers at Explore Scientific set their sights on creating a top-quality apochromatic refractor that anyone would be proud to own, they decided on using a traditional air-spaced triplet optical design in a rugged, adjustable lens cell. All materials had to be top-notch, so genuine Hoya extra-low dispersion (ED) Dense Fluor Crown (FCD1) glass was chosen, and then experienced craftsmen shaped and polished the elements that would form the foundation of a high-quality, true APO refractor.

All Explore Scientific Air-Spaced Triplet APO Refractors are diffraction-limited at 1/4 wave or better. Special EMD enhanced multi-layer coatings are deposited on all optical surfaces, and the result is bright, high contrast images with virtually no light scatter. Interferometric data on your newly purchased and registered Explore apochromatic refractor is available upon request, but time restrictions do apply, so please contact the Explore Scientific Customer Service line for more information.

While optics are the most important component of any telescope, other features, like the focuser, the finder, and the optical tube, play a crucial role in the design. Below you will find highlights on all the ingredients used to create Explore Scientific Triplet APO refractors, including a very liberal warranty that speaks volumes about the confidence that Explore Scientific has in these telescopes!

Explore Air-Spaced Triplet APO Refractor Highlights

  • Available in 80mm, 102mm, 127mm & 152mm apertures
  • Tube assemblies are available in aluminum (Essential) or Carbon Fiber editions
  • Air-Spaced Apochromatic Triplets with true APO 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.
  • Contrast 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. Sending off to the factory is an option, but is not required.
  • 80mm - 127mm models come with a heavy-duty 2" Crayford-style dual-speed 10:1 focuser
  • To attach your Explore Scientific Air-Spaced Triplet telescope to a variety of mounts, we have included the Universal Adjustable Mounting Plate. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
