Features and Benefits

The Orion 09789 StarBlast 4.5 is great for indoor viewing and semi-outdoor viewing on calm nights. On a clear night, you’ll be able to see all the way to the Andromeda galaxy and everything in between. If you train your telescope on a full Moon, you’ll get a very detailed view of the Moon’s surface, and you’ll be able to pick out landmark craters and other prominent features easily.

The device comes with the Orion EZ Finder II red-dot sight, which makes aiming and calibrating the telescope much easier. Instead calculating the exact location of the celestial object relative location to you, you can simply point the red dot sight at the star and it will be in view.

Along with the red-dot sight and standard accessories, the telescope comes with an advanced selection of high-power magnification lenses. With the add-on lenses, you can get anywhere from 15x magnification all the way up to 75x magnification. This makes the telescope an excellent choice for viewing local planets, as well as stars outside of our galaxy.

  • Comes with fast f/4 optics that make it easy to find celestial bodies
  • Expanse telescopic eyepiece has a very wide 66-degree apparent field of view
