Explore Scientific 140mm f/6.7 FPL-53 Carbon Fiber APO Triplet Refractor With 3" Hexagonal Focuser

140mm has long been considered the perfect size for an APO refractor. Explore Scientific makes that size a reality with fantastic optics and mechanics.

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 140mm FPL-53 Apochromatic Refractor.

This is an all new design from Explore Scientific and offers greater quality optics provided by Ohara. We use Ohara FPL-53 glass in these optics which is very similar in characteristics as Hoya FCD-100.

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.
