The Explore Scientific ED102 Essential Series Air-Spaced Triplet APO Refractor is a true apochromatic telescope that reveals the Moon’s stark chiseled craters, Jupiter’s orderly cloud belts, and the blue-white stars of the Orion Nebula shimmering against their misty backdrop. The ED102 opens up a treasure trove of night sky objects and offers a solid optical foundation for serious deep sky astrophotography.
Striking a perfect balance between portability and aperture, this versatile telescope delivers diffraction-limited performance with an objective size well-suited for lunar, planetary, and deep sky observation.
Its air-spaced triplet optical design virtually eliminates chromatic aberration, while HOYA FCD1 extra-low dispersion (ED) glass and EMD enhanced multi-layer coatings produce bright, high-contrast images with exceptional color fidelity.
This high-quality instrument includes two extension tubes for the 2" rack-and-pinion focuser and comes with an Explore Scientific 2N1 Hybrid Finder Scope Base pre-installed. (Finder scope not included.)
