• The Explore Scientific 127mm f/7.5 CF Triplet APO Refractor Telescope with Hoya FCD100 optics and Integrated Dew Shield is a fantastic telescope for both visual observation and astrophotography.

  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 FCD100 Series 127mm f/7.5 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 nearly identical in characteristics as OHARA's FPL-53. Relying on technological innovation, they 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-inch Hexagonal focuser with very rigid design and strong support. Up to 10-pounds of gear can be loaded onto this focuser.

  This 127mm telescope is designed to work with Explore Scientific’s 3-inch Field Flattener/0.7x Focal Reducer, though an additional adapter found here is required to thread it directly into the 127mm's stock 2.5" HEX focuser. Once you integrate the 0.7x Focal Reducer, the telescope reduces down from a 952mm f/7.5 system to be 666mm at f/5.25, which is a very fast and well-corrected system for deep sky astrophotography. If you're looking for a flat field for imaging at the full 952mm focal length, the HoTech SCA Field Flattener is a great choice.
