AR152 Air-Spaced Doublet

The Explore Scientific AR152 is a classic 6-inch (152mm) crown-and-flint achromatic refractor delivering bright, high-resolution views with true diffraction-limited optics at an f/6.5 focal ratio, excelling at revealing deep-sky objects, the Moon's detailed surface, planets, and double stars with sharp contrast. Built with heavy-duty components including a smooth 2" dual-speed focuser, a one-piece 2" diagonal with 99% dielectric coatings, and an 8x50 finderscope, this telescope is designed to withstand public star parties and educational outreach. The AR152 delivers true diffraction-limited optics, a massive 152mm aperture, and fast f/6.5 optics at a price point that makes serious astronomy more accessible than similar-aperture apochromatic telescopes. With its diffraction-limited optics, proper baffling, precision dual-speed focuser, and rugged construction, the AR152 is also a solid performer for astrophotography.
