A telescope is a great gift for families and beginners interested in space and the stars. Especially a telescope like the Orion StarBlast II 4.5 EQ. It's a genuine, real reflector telescope with sophisticated features to help inspire stargazers night after night.
With its 4.5"-diameter reflector tube and sturdy equatorial (EQ) mount with slow-motion controls, this telescope goes beyond the capabilities of smaller beginner models to support families as their interest in space grows into a lifelong appreciation of stargazing and science. The compact Orion StarBlast II 4.5 EQ is a favorite of both beginners and expert astronomers alike, thanks to its great optics, convenient portability, and easy-to-use operation.
The StarBlast II 4.5 EQ will amaze the whole family with bright views thanks to its big, 4.5"-aperture telescope tube, which collects a lot of light from the night sky to send bright, clear images of objects in space to the telescope eyepiece for viewing. The telescope's combination of short 450mm focal length and sizable 4.5" aperture means the StarBlast II 4.5 EQ will provide brighter views at any magnification compared to longer focal length telescopes, which makes it easier for everyone, and especially beginners, to locate interesting sights in the night sky. Using a telescope allows curious families to explore the sparkling night sky and search out interesting objects to observe. Use the StarBlast II 4.5 EQ to look at fascinating craters, valleys and mountains on the Moon; and bright planets like Jupiter, Saturn and Mars. Even distant objects like star clusters, brighter nebulas and galaxies can be seen in this petite reflector telescope.
