FCD100
102mm Apochromatic
Air-Spaced ED Triplet Refractor Telescope

This telescope features Japanese Hoya FCD100 optics. Relying on technological innovation, we have successfully launched the high-performance optical glass at the apex of the FCD family. Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction. Hoya FCD100 is considered the best glass ever produced by Hoya.

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, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer deposition on all optical surfaces.

In addition, this amazing little scope also includes a dual speed (10:1) 2.5" 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 102mm 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.
