Although it is far from the largest in our line of high-end refractors, the ED102mm FCD100 refractor packs a mighty punch when it comes to capturing the beauty of the cosmos. 

  Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces. In addition, this amazing little scope includes a 2.5" hexagonal focuser with very rigid design and strong support. 

  Although it is a standout imaging telescope on its own, the 102mm is compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties.
