Open Box Explore Scientific FCD100 127ED Triplet

Expose the wonder of Earth's celestial neighborhood with the Explore Scientific 127mm FCD100 Refractor. You'll experience the beauty of the barren lunar landscape, the smooth elegance of Saturn's ring structure, the most luminous deep sky objects in the Messier catalog, and more!

For all intents and purposes, the 127mm FCD100 is the same instrument as the Explore Scientific 127mm Essential Series Refractor, but with higher quality optics. Explore Scientific uses Hoya FCD100 extra-low dispersion (ED) glass which has characteristics analogous with Ohara FPL-53 glass. With a true diffraction-limited optical design and compact size, the 127mm FCD100 is a premium quality refractor that has been made to inspire impromptu stargazing adventures.

By combining Hoya FCD100 optics with Explore Scientific's proprietary EMD enhanced multi-layer coatings on all optical surfaces, the 127mm FCD100 air-spaced triplet refractor produces radiant images with high contrast while avoiding chromatic aberrations almost entirely.

This incredible little scope also comes with a 2.5" Hexagonal focuser that features an extremely rigorous design and support for up to 10 lbs. of accessories.

Even though the 127mm FCD100 is an outstanding telescope by itself, it is also small enough to mount on a larger instrument. This gives you flexibility when astro-imaging by splitting guiding and imaging responsibilities between the two scopes.
