Lightweight and portable at just 11.5 lbs, this telescope is perfect for public star parties, educational outreach, or personal stargazing adventures. Built with professional-grade components including a smooth two-speed 2" Crayford focuser, a dielectric-coated 2" diagonal, and an 8x50 straight-through finderscope mounted on a quick-release hybrid finder base, it offers reliable performance and easy setup.
