What We Like About the Celestron Cometron FirstScope Telescope


  • The wide field of view on this 76mm Celestron FirstScope telescope let you gaze at large objects, like a comet, a section of the Milky Way, or a star cluster, in their entirety.


  • The Celestron Cometron FirstScope is a cinch to set up and use! Just place it on a table or other stable surface and you're ready to go.


  • Due to its simple design, this is a great telescope for youngsters. There is no tripod to trip over, but the 3" mirror will show you more than most beginner refractors!


  • You get two eyepieces (they provide the magnification) and a finder with this portable telescope, but you can always add more eyepieces later on.

More About the Celestron 76mm Cometron FirstScope Telescope


Be ready for the next big comet with Celestron’s special-edition Cometron FirstScope, 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. The Celestron FirstScope 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 Celestron Cometron FirstScope offers several upgrades from the original Celestron FirstScope, including two Kellner eyepieces and a 5x24 finderscope. Weighing just 4.3 pounds, the Cometron FirstScope 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.
