The Explore Scientific ED102 Essential Series Air-Spaced Triplet APO Refractor Telescope is a true apochromat refractor that reveals our Moon’s stark chiseled craters, Jupiter’s orderly cloud belts and the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home. The ED102 Essential Series Apochromatic Refractor will open up a treasure trove of night sky treats, and provide a solid optical platform to begin serious deep sky astrophotography.

A nice compromise between portability and aperture, this versatile high-end telescope offers true diffraction-limited optics and has an objective lens size that performs well in lunar, planetary and deep sky viewing situations.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD1 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings.

Comes with 2 extension tubes for the 2" rack-and-pinion focuser and the Explore Scientific 2N1 Finder Scope Base installed on scope. (Finder scope not included. Add the Explore Scientific 8x50 Straight Through Illuminated Viewfinder or the Explore Scientific 8x50 Illuminated Right Angle Polar Finder Scope)
