Explore Scientific ED 102mm f/7 FCD100 Series Air-Spaced Triplet Refractor Telescope - FCD100-10207-02

Introducing the Explore Scientific presents the ED 102mm f/7 FCD100 Series Air-Spaced Triplet Refractor Telescope, a gateway to the wonders of the cosmos.

Delve into the hauntingly beautiful lunar landscape, behold the graceful elegance of Saturn's resplendent rings, or explore the brilliant gems of the Messier catalog with the exceptional 102mm FCD100 Apochromatic Refractor Telescope.

This telescope shares its lineage with the ES-ED10207-02 model but elevates your astronomical experience with superior optical precision.

We harness the power of Hoya FCD100 optics, which bear remarkable similarities to Ohara FPL-53 glass.

Through relentless technological innovation, we have achieved mass production of this premium optical glass, proudly standing at the pinnacle of the FCD family.

By combining it with high refractive index glass, we attain an unrivaled level of chromatic aberration correction.

Hoya FCD100 stands as a testament to Hoya's finest glass craftsmanship.

With its true diffraction-limited optical design and a compact size designed to inspire impromptu stargazing adventures, this telescope is the ideal companion for celestial exploration.

The air-spaced triplet optical configuration virtually eradicates chromatic aberrations, ensuring the creation of exquisite high-contrast images.

This feat is accomplished by the harmonious union of genuine HOYA FCD100 extra-low dispersion (ED) glass and our proprietary EMD enhanced multi-layer coatings meticulously applied to every optical surface.

This remarkable telescope boasts a 2.5" Hexagonal focuser renowned for its robust design and unwavering support, capable of accommodating up to 10 lbs of equipment.

While it shines brilliantly on its own, the 102mm telescope's compactness also allows it to be mounted on a larger telescope, offering versatility to your astrophotography endeavors by separating guiding and imaging functions.



  • 102mm Objective Lens: The telescope features a 102mm (4 inches) diameter objective lens, which determines its ability to gather light for clear and detailed observations.
  • 200x Highest Useful Magnification: This telescope can enlarge celestial objects up to 200 times their normal size, enabling precise and close-up examination of planets, lunar characteristics, and various astronomical phenomena.

  • 714mm Focal Length: This telescope offers powerful magnification for studying planets, the moon's surface, and deep-sky objects. It also enhances image quality for astrophotography when used with the appropriate gear.

  • Air-Spaced Triplet Design: This telescope uses an air-spaced triplet lens design, consisting of three lens elements, to minimize chromatic aberration and produce high-quality, color-corrected images.
  • FCD100 Extra-Low Dispersion Glass: The telescope likely incorporates FCD100 (Ohara) extra-low dispersion glass elements to reduce chromatic aberration further and provide excellent color fidelity.
  • Apochromatic Performance: The triplet lens design, coupled with the FCD100 glass, ensures apochromatic (APO) performance, which means it delivers sharp, true-color images with minimal color fringing.
  • Multi-Coated Optics: Explore Scientific telescopes typically come with multiple layers of anti-reflective coatings on the lenses to improve light transmission and enhance image contrast.
  • 2.5-Inch Dual-Speed Rack-and-Pinion Focuser: A 2.5-inch dual-speed focuser with a rack-and-pinion design allows for precise focusing and fine adjustments when observing celestial objects.
  • Dew Shield: A retractable dew shield helps prevent moisture buildup on the objective lens during dewy conditions, maintaining image quality.
  • Aluminum Tube: The telescope is likely housed in a sturdy and lightweight aluminum tube, which provides durability and portability.
  • Mounting Options: The telescope may be compatible with various mounting options, such as equatorial mounts or alt-azimuth mounts, depending on your preference and intended use.
