Explore Scientific ED80 Carbon Fiber Edition Telescope

The Explore Scientific ED80 Carbon Fiber Edition is an ideal telescope for wide field observing or astro-imaging on a budget. With its 480mm focal length this telescope is capable of producing and incredibly wide five degree true field for either visual observing or astrophotography. The light weight of this instrument is also less taxing on the telescope mount, which can be a key consideration for imaging applications. This telescope is a fine choice for beginning astrophotographers wishing to spend under $1000 on an optical tube.

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 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. Interferometic data on your newly purchased and registered Explore apochromatic refractor is available upon request. Time restrictions apply; please contact Customer Service at Explore Scientific for more information.

While optics are definitely the most important component of any telescope, other features, like the focuser play a crucial role in the design. Below you will find highlights on all of 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 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
  • 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 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.
