The Explore Scientific ED102 is a 102mm air-spaced triplet apochromatic refractor that strikes an ideal balance between aperture, portability and performance. With extra-low dispersion glass in a three-element design, the ED102 delivers sharp, high-contrast, color-corrected views that make it one of the most versatile 102mm refractor telescopes available.
At 102mm, the ED102 gathers noticeably more light than an 80mm refractor, revealing finer planetary detail, more stars in clusters and brighter views of nebulae and galaxies, while remaining light enough for travel and quick setups. For astrophotography, its color-free optics produce clean, natural-looking images when paired with a field flattener or focal reducer. For visual observing, it delivers crisp views of the Moon, planets and double stars at high magnification.
The ED102 is available in Essential Series and FCD100 Series configurations, in aluminum and carbon fiber, and in packages with the iEXOS-100 PMC-Eight tracker for a complete imaging system. Add a dielectric star diagonal and wide-field eyepieces for visual use. Whether you are starting in astrophotography or upgrading your refractor, the ED102 triplet is a proven, highly capable choice.
