Product Description

Explore Scientific ED102 Carbon Fiber Triplet Refractor Telescope

The Explore Scientific 102mm ED Carbon Fiber triplet refractor telescope utilizes premium Hoya FCD1 glass to create this 4" refractor telescope resulting in excellent color, contrast and brilliance.  the Explore Scientific EDT 102 is a perfect choice for the observing and imaging astronomer alike and includes a push/pull collimation cell, two speed precision focuser and a 2" 99% reflectivity diagonal.   Included cradle rings have a built in handle for easy transport and handling with a V series dovetail to easily fit a wide variety of mounts.   The carbon fiber finish of the optical tube helps resist fluctuations with temperature changes, reducing the need to refocus throughout the night and making the Explore Scientific 102mm surprisingly lightweight at just 7 pounds.

Explore ED102 Air-Spaced Triplet Refractor Highlights…

  • Tube assemblies are available in carbon fiber
  • Air-Spaced Apochromatic Triplets…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.
  • Included 2" diagonal has a precision-polished mirror with enhanced 99% dielectric coatings.
  • To attach your Explore Scientific 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.


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.
