Explore Scientific 80mm Carbon Fiber f/6 Triplet Refracting Telescope - DISCONTINUED -

This 80 mm (3.15-Inch) Aperture f/6 Carbon Fiber Triplet OTA by 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.

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-Inch, 99-Percent Reflective, Dielectric-Coated Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the diagonal flat mirror, insuring precision alignment.

On pristine nights of steady seeing, Saturn's Rings can forever affect the hearts and minds of almost anyone who lays eyes on them. It is nights like these that astronomers like to set up their refractors and push the magnification to the limits, not only to see the magnificence of the planet at greater scale but to really test the optical and mechanical quality of the telescope. Many telescopes are only supplied with a standard single-speed focuser, you will find that a tiny nudge will throw out focus and turn your night into one of frustration. So included as standard equipment, on all Explore Scientific ED Series, a Dual-speed focuser with tension adjustment and lock to obtain and hold perfect focus.

EMD (Enhanced Multi-layer Deposition) Coatings eliminate 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 masks and deflects unwanted stray light.
