Orion StarBlast 4.5 Equatorial Reflector Telescope
Our compact, performance-packed Orion StarBlast 4.5 EQ Reflector telescope is a favorite of both beginners and expert astronomers alike. It combines the much-heralded Orion StarBlast 4.5” wide-field (f/4.0) parabolic reflector optics with our sturdy EQ-1 equatorial tracking mount and adjustable-height tripod.
-A wide-field reflector telescope with enough aperture to get great views of the Moon, planets, and many bright deep-sky objects
-A fantastic general-purpose astronomical telescope - great for the beginner to test the waters with mirror optics large enough to keep you and your family busy viewing for years to come
-Works amazingly well with the included Expanse telescope eyepieces which yield a very wide 66° apparent field of view - your first look at the Andromeda galaxy will knock your socks off!
-Fast f/4 optics and a short focal length provide a very wide field of view, making it easy to locate celestial objects without having to hunt around
-The EQ-1 equatorial telescope mount makes tracking night-sky objects extremely easy using the included slow-motion controls. Also includes an EZ Finder II reflex sight for easy aiming, 15mm and 6mm 1.25" Expanse eyepieces, collimation cap, Starry Night software, and more!
