Overall Customer Rating

Be ready for the next big comet with Celestron's special-edition Cometron Telescope, a compact, lightweight telescope that's perfect for beginners looking to experience the magic of a dazzling comet, planet, or nebula. This tabletop Dobsonian-style telescope includes a spherical mirror with a generous 76mm of aperture. This Telescope provides bright, sharp views of comets and other celestial objects, and renders the Moon's mountains and craters in crisp detail. And thanks to its wide field of view, you'll be able to observe the brightest part of the comet and its tail or favorite deep-sky objects like the Orion Nebula.

The Cometron FirstScope offers several upgrades from the original Telescope, including 2 Kellner eyepieces and a 5x24 finderscope. Weighing just 4.3 pounds, this Cometron telescope is a tabletop telescope that you can take on all your outdoor adventures. It's also stylish enough to be a decorative fixture on your bookshelf or desk.
