Telescope-Refracting Telescopes-Explore Scientific 80 mm f/6 FCD100 Air-Spaced Triplet Refractor with 2.5″ HEX Focuser

Explore Scientific ED80 f/6 Triplet Refractor OTA

The Explore Scientific 80 mm f/6 ED Air-Spaced Triplet Refractor Telescope has Hoya FCD100 optics for beautifully sharp, high contrast images. The optical tube assembly is painted classic white, and includes an integrated dew shield on one end and a 2.5″ HEX, or hexagonal, Crayford-style focuser. The telescope attaches easily to Vixen-style mounts with the built-in Vixen dovetail foot. Accessories include a hybrid finder scope base, which comes already attached to the tube, and an Explore Scientific 2″ Diagonal, with 99% reflectivity to compliment the optics of this portable, classic refractor. Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies.

The hybrid finder scope base can accept all legacy Explore Scientific finder scope brackets, as well as the mini dovetail type (Vixen, Synta, Celestron). Made of rugged, black anodized metal with chrome-plated metal screws.

This scope is similar to the ES-ED0806-01 but offers superior quality optics. The Hoya FCD100 optics in this OTA are similar to the Ohara FPL-53 used in the ES-ED0806-01. However, the Hoya FCD100 gives the observer high-performance optical glass at the apex of the FCD family. Combining it with optical glass of high refractive index allows the scope to achieve unprecedented advanced chromatic aberration correction. Hoya FCD100 is considered the best glass ever produced by Hoya.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

In addition, this amazing little scope also includes a 2.5″ Hexagonal 10:1 dual-speed focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser. An integrated dew shield also helps keeps your optics at peak performance, even in the wee morning hours.

Although it is a standout telescope on its own, the 80mm also is compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties.
