Sale price$1,699.99

The Explore Scientific ED102-FCD100 Series Air-Spaced Triplet Refractor delivers premium optical performance in a compact, portable design ideal for both visual astronomy and astrophotography. Its advanced air-spaced triplet lens system uses genuine HOYA FCD100 extra-low dispersion (ED) glass—comparable in quality to Ohara FPL-53—and a high refractive index element to achieve exceptional chromatic aberration correction and true color fidelity. With diffraction-limited optics and proprietary EMD enhanced multi-layer coatings on all optical surfaces, the ED102 produces brilliant, high-contrast views of the Moon, planets, and deep-sky objects. Its 102mm aperture and 714mm focal length provide a versatile balance between wide-field viewing and detailed high-magnification performance. The precision 2.5" HEX focuser offers smooth, stable focusing and supports imaging setups up to 10 lbs. Lightweight at only 12 lbs, the ED102 is an excellent grab-and-go telescope and can also serve as a high-quality auxiliary scope on larger instruments for guiding and imaging versatility.
