The Orion StarBlast 4.5 EQ reflector telescope is suitable for beginner and intermediate astronomers. It comes with an equatorial tracking mount and adjustable-height tripod. Two eyepieces from the Orion Expanse series, which have a large 66 degree apparent field of view, are included. A 15mm Expanse eyepiece provides 30x power magnification, and a 6mm Expanse eyepiece provides 75x magnification.  An Orion EZ Finder II reflex sight is provided to aim the StarBlast 4.5 Equatorial Reflector Telescope anywhere in the night sky. The EZ Finder II projects a small red-dot onto a viewing window and the user must move the telescope until the red-dot is aimed at the intended area of the sky
