Explore Scientific 102mm FCD100 f/7 Apochromatic Refractor

Transport yourself to the rocky surfaces of the Moon or study with the swirling beauty of Jupiter's stormy atmosphere with the Explore Scientific 102mm FCD100 APO refractor telescope. An excellent choice for observers and imagers, the 102mm FCD100 is also lightweight enough to ride on top of larger imaging telescopes to serve as a premium guide scope or secondary imaging telescope.

Based on the Explore Scientific triplet refractor design, and building on the incredible optical quality, the FCD100 series uses one of the best types of optical glass - Hoya FCD100. Similar to Ohara FPL-53 glass, FCD100 provides a true diffraction limited design. With an air-spaced triplet design, the FCD100 series eliminates chromatic abberations for jaw-dropping brilliant contrast and gorgeous color rendition thanks to extra low dispersion glass and Explore's own EMD enhanced multi-layer coatings on all optical surfaces. The all aluminum optical tube is has interior flat black coatings to eliminate unwanted reflections and provides a stable and durable housing for the FCD100 lens elements.

To further enhance your observing and imaging sessions, the 127mm FCD100 features an Explore Scientific 2.5" Hexagonal focuser which can support up to 10 pounds without slipping or flexure.
