Orion StarBlast 4.5 Astro Tabletop Dobsonian Telescope

The StarBlast  4.5 is a 113 mm (4.45-Inch) Aperture Tabletop Reflector Telescope by Orion:


Maybe because many of us started out with those frustrating little department store refractors, but Orion strives to offer quality telescopes for youngsters that are easy to use and will inspire their natural inclination to explore. The Orion StarBlast is one such telescope. Pint-sized in stature, it's a real reflecting telescope that is super-simple to use and yet manufactured with the kind of quality you'd expect in more expensive models.

The Orion StarBlast 4.5 is a point-and-view telescope that swivels smoothly on its sturdy, low-profile base. No complicated setup is required. In fact, it comes pre-assembled and ready for action right out of the box! Just carry it outdoors by its built-in handle, place it on the ground or on a picnic bench, and let the fun begin!

Inside the Orion StarBlast's 18-inch-long steel tube are real, quality telescope optics, including a 113 mm (4.5-inch) parabolic mirror. With the two Explorer II eyepieces, kids will see spectacular views of the Moon's craters, the planets, star clusters, and lots of other exotic space stuff. Aiming the StarBlast is easy with the EZ Finder II red dot finder scope. The package also includes an eyepiece rack and a snap-on dust cap.

The Orion StarBlast will not only give kids hour after hour of fun, but will also nurture their interest in the night sky by giving them a rugged, usable telescope. One-year limited warranty.
