    Explore Scientific CF 102mm F/7 Triplet

    The Explore Scientific 102mm APO refractor delivers exceptional image clarity and color making it a perfect choice for the observer and imager alike. Striking a perfect compromise between portability and aperture, this scope offers a healthy 4 inches of light-gathering aperture and true diffraction-limited optics. At this objective, the 102mm performs well in lunar, planetary and deep sky viewing scenarios.

    Offering an air-spaced triplet HOYA ED glass optical design which is virtually free of any chromatic aberrations, the image is bright and high in contrast. Proprietary EMD enhanced multi-layer coatings on all optical surfaces further enhance the optics' native performance. Striking a happy medium with a f/7 focal ratio, color and contrast are optimized without sacrificing exposure time.

    With a carbon fiber optical tube, the Explore Scientific 102mm maintains a lightweight and is very temperature stable. Unlike aluminum and steel tubes which shrink and expand with temperature changes, a carbon fiber tube will eliminate focus changes. A push-pull collimation cell ensures that your scope is always as sharp as possible, and a two-speed precision focuser will help you bring those planets and star clusters into tack sharp focus.
