Reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog with Explore Scientific’s 165mm FPL-53 Apochromatic Refractor.

This is an all new design from Explore Scientific and offers greater quality optics provided by Ohara. We use genuine Ohara FPL-53 ED opical glass in these optics.

Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction. Ohara FPL-53 is considered the best glass ever produced by Ohara. Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine Ohara FPL-53 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

In addition, this amazing scope also includes a 3″ Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser.

ED165mm f/7 Air Spaced Triplet with Ohara FPL-53 optics and Integrated Dew Shield; 1155mm focal length; 3″ Starlight FeatherTouch Focuser; Cradle Ring with Handle and Vixen Style Dovetail Plate; Explore Finder Scope Base installed on scope; 99% Reflective 2″ Diagonal; and a hard TSA approved carrying case. Weighs 15lbs. (Finder Scope NOT Included)

APO TRIPLET SERIES

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.

Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. Telescope objective lenses for wide-band digital imaging in astronomy must have apochromatic correction, as the optical sensitivity of typical CCD imaging arrays can extend from the ultraviolet through the visible spectrum and into the near infrared wavelength range. Apochromatic designs require optical glasses with special dispersive properties to achieve three color crossings. Explore Scientific achieves this using high-quality ED (Extra-Low Dispersion) glass from Hoya and Ohara.
