Explore Scientific 102mm FCD100 Apo Refractor

The Explore Scientific 102mm FCD100 is a 102-mm f/7 apochromatic refractor featuring an air-spaced triplet optical design.

It also features Hoya FCD100 optics that virtually eliminates chromatic aberrations. With this incredible telescope, you can reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog.

About the Explore Scientific 102mm Apo

Explore Scientific’s 102mm Apochromatic Refractor is essentially the same scope as the ES-ED10207-01 but offers greater quality optics. We use Hoya FCD100 optics, which is very similar in characteristics as Ohara FPL-53. 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.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, the Explore Scientific 102mm f/7 Apo 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. Additionally, this incredible little scope also includes a 2.5" Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser.

Although it is a standout telescope on its own, the Explore Scientific FCD100 102mm is also compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties.
