The Orion StarBlast 4.5 EQ reflector telescope is suitable for beginner and intermediate astronomers. It comes with a sturdy EQ-1 equatorial tracking mount and adjustable-height tripod. Included are two eyepieces from the Orion Expanse series - a 15mm and 6mm - which have a large 66 degree apparent field of view. The included 15mm Expanse telescope eyepiece provides 30x power magnification, while the 6mm Expanse eyepiece bumps up the power all the way to 75x magnification.  An included Orion EZ Finder II reflex sight makes it easy to effectively 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 so all you have to do is move the telescope until the red-dot is aimed at the area of sky you wish to view through the telescope.


  • Best for viewing: The moon and planets like Jupiter and Saturn
  • User level: Beginner and intermediate
  • Optical design: Newtonian reflector

Note: This is a good telescope for beginners to learn how to operate a simple and manual telescope.  It does not come with a computer nor a motorized tracking system, so there is less to learn.  It is not heavy and quite portable.  Some assembly and setup is required.  It is a good telescope for children, with adult supervision, to get started with Astronomy.
