• From our Moon's chiseled craters to Jupiter's orderly cloud belts to the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home, Explore Scientific's 102mm Apochromatic Refractor can open up a treasure trove of night sky treats.
  
  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 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.
