Discover the hobby of astronomy with the COSMOS FirstScope. It doesn’t get much simpler or more portable than COSMOS FirstScope’s tabletop Dobsonian design. Just remove it from the box, attach the finderscope, insert an eyepiece, and you’re ready to view the Moon, planets, nebulae, comets, and more!

COSMOS FirstScope’s Newtonian reflector optical system features a spherical mirror with a generous 76 mm of aperture. You’ll get bright, sharp views of celestial objects, and observe the Moon’s mountains and craters in crisp detail. Thanks to COSMOS FirstScope’s wide field of view, you'll be able to observe expansive views of the sky which include open star clusters, comets, or favorite deep-sky objects like the Orion Nebula.

This special edition of our bestselling FirstScope offers several upgrades over the original, including 2 Kellner eyepieces and a red dot StarPointer finderscope. Since it weighs just 4.3 pounds, the COSMOS FirstScope is the perfect companion for camping trips, and all your outdoor adventures.

Inspired by COSMOS: A SpaceTime Odyssey, the telescope tube is adorned with a custom, special-edition wrap featuring the COSMOS eye nebula design. When not in use, this unique telescope is stylish enough to be a decorative fixture on your bookshelf or desk. You’ll also receive a beautiful Cosmic Calendar poster with images from the show, and a free planetarium app for your iPhone, iPad, or Android device.
