Explore Scientific AR152 Air-Spaced Doublet Refractor

Explore Scientific AR152 Air-Spaced Doublet Refractor Telescope - Discover the wonders of the universe! Description Large high-resolution aperture for a refractor with diffraction-limited wide field optics and competes favorably with much larger aperture Schmidt-Cassegrain telescopes; Excellent visual views of deep sky objects; Advanced-Level Quality Construction and Components The Explore Scientific AR152 Air-Spaced Doublet, is a classic air-spaced, crown-and-flint doublet achromatic refractor, and at 152mm (6-inches) of aperture, it provides the brightest images and highest resolution of the AR Series. Our design goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field (f/6.5) large aperture refractor. Images of deep-sky objects are stunning at low powers and all at a small fraction of the price you would pay for a similar aperture apochromat refractor. At high power, the moon, plan
