  • 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 with Explore Scientific’s ED127-FCD100 Air-Spaced Triplet in lightweight Carbon Fiber!
  • This telescope has all the great features of the original EDT-127075-CF but includes genuine HOYA’s premium FCD100 ED glass which is very similar in characteristics as OHARA’s FPL-53. Relying on technological innovation, we have successfully launched the mass production of 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 one of the premier ED glass types available.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 coatings on all optical surfaces.
  • In addition, this amazing scope also includes a new 2.5″ Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser. ED127 Carbon Fiber f/7.5 Air Spaced Triplet with HOYA FCD100 optics and Integrated Dew Shield; 952mm focal length; 2.5″ HEX Focuser; Cradle Ring with Handle and Vixen Style Dovetail Plate; Explore Finder Scope Base installed on scope; 99% Reflective 2″ Diagonal. Weighs 14lbs. (Case and Finder Scope NOT Included)

Description

EXPLORE SCIENTIFIC 127MM FCD100 F/7.5 ED APO TRIPLET REFRACTOR W/ 3″ FT FOCUSER

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.

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.

APO TRIPLET SERIES

Apochromatic (ED APO) lenses are designed to bring all the colors into focus in the same plane where as Achromatic lenses are corrected to bring two wavelengths into focus in the same plane.

Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. Telescope objective lenses for wide-band digital imaging in astronomy must have apochromatic correction, as the optical sensitivity of typical CCD imaging arrays can extend from the ultraviolet through the visible spectrum and into the near infrared wavelength range. Apochromatic designs require optical glasses with special dispersive properties to achieve three color crossings. Explore Scientific achieves this using high-quality ED (Extra-Low Dispersion) glass from Hoya and Ohara.
