Explore Scientific 115 mm FPL-53 ED APO Triplet Refractor


This 115 mm FPL-53 Apochromatic Refractor from Explore Scientific displays night sky marvels such as the serene beauty of Saturn's rings, the gorgeous barren lunar landscape, or the brightest deep sky gems of the Messier catalog.

Explore Scientific's all-new design provides higher quality Ohara optics. Ohara FPL-53 glass is used to give this refractor optical characteristics similar to the Hoya FCD-100.

This combined with a high refractive index allows for exceptional advanced chromatic aberration correction. Ohara FPL-53 is thought to be the finest glass Ohara has ever produced. With a true diffraction-limited optical design, as well as a compact size ideal for stargazing on a whim, this supreme quality refractor is the optimal grab-and-go instrument for celestial exploration.

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.

Additionally, this incredible scope also comes with a rigidly designed 3" Hexagonal focuser that supports a gear load of up to 10 lbs.
