EXPLORE SCIENTIFIC 102MM F/7 ESSENTIAL SERIES APO TRIPLET REFRACTOR – NO CASE

From our Moon’s chiseled craters to Jupiter’s orderly cloud belts to the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home, Explore Scientific’s 102mm Apochromatic Refractor can open up a treasure trove of night sky treats.

A nice compromise between portability and aperture, this versatile high-end telescope offers true diffraction-limited optics and has an objective lens size that performs well in lunar, planetary and deep sky viewing situations.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

Description

Explore Scientific 102mm f/7 Essential Series APO Triplet Refractor Features…

  • The Explore ED102 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.
  • 102mm models come with heavy-duty 2″ dual-speed focusers.
  • The 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.

APO TRIPLET SERIES

Apochromatic (ED APO) lenses are designed to bring all the colors into focus in the same plane where as Achromatic lenses are corrected to bring two wavelengths into focus in the same plane.

Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. Telescope objective lenses for wide-band digital imaging in astronomy must have apochromatic correction, as the optical sensitivity of typical CCD imaging arrays can extend from the ultraviolet through the visible spectrum and into the near infrared wavelength range. Apochromatic designs require optical glasses with special dispersive properties to achieve three color crossings. Explore Scientific achieves this using high-quality ED (Extra-Low Dispersion) glass from Hoya and Ohara.
