About the Explore Scientific ES- ED10207-01

The Explore Scientific 102mm f/7 Classic White "Essential Series" Air-Spaced Triplet ED Apochromatic Refractor Telescope is a perfect instrument for demanding wide field observing and astrophotography. Rugged and portable, the Explore ED Triplet is a true three-element apochromatic telescope capable of producing research-level image quality.

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.

Deluxe Two-Speed Focuser
ES has included as standard equipment, on all Explore Scientific ED Series, a two-speed Crayford-style precision focuser with tension adjustment and lock to obtain and hold perfect focus.

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.

Explore Scientific ES- ED10207-01 Includes

  • Explore Scientific 102mm f/7 ED Apochromatic Triplet Essential Refractor Telescope
  • 2" Dual-Speed Rotatable Focuser
  • "Vixen-style" Dovetail
  • 2" Diagonal
  • 1.25"Compression Ring Adapter
  • Explore Scientific Warranty

Explore Scientific ES- ED10207-01 Features

  • The Explore ED102 Essential Edition telescope comes with a white aluminum tube with black accents.
  • Explore Scientific Air-Spaced Apochromatic Triplets have true APO optic and are diffraction limited at .25PV or better.
  • Genuine ED glass from Hoya Japan is used on all ED APO Triplets at Explore, for superb quality and light throughput.
  • Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter; and 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 your ED102 Triplet off to the factory is always an option, but is not required.
  • 102mm models come with a heavy-duty 2" dual-speed rotatable focuser, including 2 draw tube extensions.
  • To attach your Explore Scientific Air-Spaced Triplet telescope to a variety of mounts, a "Vixen-style" dovetail is included. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
