DESCRIPTION

Explore Scientific FPL-53 Series 165mm f/7 Triplet Refractor

The ED165-FPL53 f/7 Air-Spaced Triplet Apochromatic Refractor Telescope is Explore Scientific's largest refractor telescope. It incorporates their true three-element apochromat design, the ED165-FPL53, with an aperture of 165 mm (6.5-inch) utilizes one of the highest performance extra-low dispersion materials obtainable: Ohara FPL-52 ED Glass.

Combining FPL-53 with optical glass of high refractive index allows this telescope to achieve unprecedented advanced chromatic aberration correction. OHARA FPL-53 is considered one of the best glass types ever produced. Having a true Diffraction-Limited (DL) optical design, this large high-performance refractor  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.
