The Zhumell Z100 Portable Reflector Telescope features a 100mm parabolic primary mirror, a high-end feature that's very uncommon in telescopes of this size. The parabolic mirror removes visual defects like spherical aberration, providing noticeably sharper views. You can count on more than 90 percent light transmission, for brighter views of even dim objects like nebulae. This compact, portable tabletop Dobsonian comes with two fully multi-coated eyepieces and a red dot finderscope, making it an excellent choice for beginners and experienced observers seeking a grab-and-go reflector for lunar, planetary, and deep-sky observation.
