Explore Scientific ED80mm FCD100 f/6 Air-Spaced APO Triplet Refractor

Discover the Explore Scientific ED 80mm - FCD100 Series Air-Spaced Triplet Refractor Telescope, your gateway to the celestial wonders of our universe.

Immerse yourself in the stark beauty of lunar landscapes, the tranquil elegance of Saturn's rings, and the dazzling brilliance of the Messier catalog's deep-sky treasures, all through the lens of Explore Scientific's 80mm FCD100 Apochromatic Refractor.

This remarkable telescope shares its lineage with the ES-ED0806-02 but elevates your stargazing experience with superior optical quality.

Harnessing the precision of Hoya FCD100 optics, closely resembling Ohara FPL-53 glass, we've embarked on a journey of technological innovation.

Our achievement? The mass production of high-performance optical glass at the pinnacle of the FCD family.

This, combined with high-refractive-index optical glass, grants us unrivaled mastery over advanced chromatic aberration correction. Hoya FCD100 stands as the pinnacle of Hoya's glass craftsmanship.

Designed with a genuine diffraction-limited optical system and dimensions that beckon spontaneous stargazing sessions, this high-quality telescope is the quintessential grab-and-go companion for celestial exploration.

Furthermore, this astonishingly compact telescope features a 2.5" Hexagonal focuser, renowned for its unwavering stability and robust support, capable of accommodating up to 10 lbs. of equipment.

While it shines as a standalone telescope, the 80mm is also sufficiently compact to be mounted onto a larger telescope, enhancing the versatility of your astrophotography endeavors by dividing the guiding and imaging roles. The telescope tube boasts an outer diameter of 91mm.
