The Explore Scientific ED127 Carbon Fiber Edition is a large aperture apochromatic refractor that weighs just over 14 pounds. 

The Explore Scientific ED127 Carbon Fiber Edition is a large 5-inch apochromatic refractor using a modern lightweight carbon fiber tube. This telescope includes a two-inch two-speed focuser, two-inch dielectric diagonal, tube rings with Vixen style dovetail. If you are looking for a big apochromatic refractor without an equally big price tag, then the Explore Scientific ED127would be a good place to start. This telescope combines excellent mechanical construction and optics. With a full five inches of unobstructed aperture, this telescope is equally at home when observing the moon, planets, double stars or deep space objects.

We get a lot of questions concerning the differences between aluminum tube and carbon fiber editions of the same telescope. For most practical purposes, the only factor to be concerned with is the weight. That can be significant with larger telescopes such as this one. Keep in mind that heavier telescopes also require heavier mounts with greater instrument capacity. The weight of this telescope is easily accommodated by relatively inexpensive mounts, such as the Celestron Advanced VX or Orion SIrius EQ-G.

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
  • The 152mm model comes with a special edition 3" rack & pinion dual-speed 10:1 focuser, made for Explore Scientific by Starlight Instruments. A 2" compression ring adapter is included.
  • 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.
  • 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.
