Used Explore Scientific Essential 102mm F/7 Triplet-FCD1 -SOLD-

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.

Apochromatic (ED APO) lenses are designed to bring all the colors into focus in the same plane where as Achromatic lenses are corrected to bring two wavelengths into focus in the same plane. 

FCD-1 is manufactured by Hoya in Japan. This glass is used in the FCD-1 ED Essential and Carbon Fiber Series Apochromatic high-performance refractors.

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 an f/7 focal ratio, color and contrast are optimized without sacrificing exposure time.


 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.
