The Explore Scientific AR102 delivers stunning, high-contrast views through its classic 102mm crown-and-flint doublet design with a fast f/6.5 focal ratio. Lightweight and portable at just 11.5 lbs, this telescope is perfect for public star parties, educational outreach, or personal stargazing adventures. It includes professional-grade components including a smooth two-speed 2" Crayford focuser, a dielectric-coated 2" diagonal, and an 8x50 straight-through finderscope. The doublet achromatic lens system virtually eliminates chromatic and spherical aberrations, making this refractor ideal for lunar and planetary observation, as well as bright deep-sky objects.
