Product Details

  • The Orion StarBlast II 114 mm (4.5-Inch) Aperture EQ Reflector Telescope is a great gift for those interested in space and the stars. Especially a telescope like the Orion StarBlast II 4.5 EQ. It's a real reflector telescope with sophisticated features which will help inspire beginning stargazers night after night.

    With its 4.5-inch diameter reflector tube and sturdy equatorial (EQ) mount with slow-motion controls, this telescope goes beyond the capabilities of smaller beginner models to support amateur astronomers as their interest in space grows into a lifelong appreciation of stargazing and science. The compact Orion StarBlast II is a favorite of both beginners and expert astronomers alike, and stargazers won't outgrow the telescope 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-inch 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 450 mm focal length and sizable 114 mm (4.5-inch) 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 backyard stargazers to explore the sparkling night sky and search out interesting objects to observe. Everyone in the family will enjoy using 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.


    Let's take a closer look at all the great accessories you'll get with the StarBlast II 4.5 EQ telescope:


    Start stargazing with the 25mm Sirius Plossl eyepiece.

    The included 25mm Orion Sirius Plossl eyepiece provides an 18-power view in the StarBlast II 4.5 EQ with a 52° apparent field of view. The 25mm Sirius Plossl is a great eyepiece to use first when you use the telescope each night, since it provides a larger, less magnified window of night sky for you to view. This lower magnification makes it easy to find interesting objects in the night sky.


    Increase magnification with the 10 mm Sirius Plossl eyepiece for more powerful views. After you've scanned the skies with the 25 mm Sirius Plossl ocular in the StarBlast II 4.5 EQ, take a closer look at interesting objects by swapping out the 25 mm eyepiece with 10 mm Sirius Plossl to boost magnification up to 45x. The more powerful view in the 10 mm focal length eyepiece makes it easier to see details such as craters and mountains on the Moon, as well as details of bright planets like the moons of Jupiter and the rings of Saturn.
    The included Orion EZ Finder II red-dot sight makes aiming the telescope nice and "EZ". The Orion EZ Finder II reflex sight lets you aim the StarBlast II 4.5 EQ Reflector Telescope anywhere in the night sky. Following a simple alignment procedure, 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 want to see in the telescope.
    Use the Orion MoonMap 260 to learn more about the lunar features you see in the telescope. With locations and names of over 260 features on the Moon such as craters, mountains, valleys, "seas" and more, the included Orion MoonMap 260 is a great tool for beginning astronomers. This detailed map will even show you where various spacecraft have landed on the Moon's surface! The MoonMap 260 can be used to plan what to look at on the Moon, and to learn the official names of all the interesting lunar landscape features you see in the StarBlast II 4.5 Reflector Telescope.

    The 4.5" telescope tube is supported by the sturdy Orion EQ-1 mount and an adjustable-height tripod. Since stars and other night sky objects appear to move across the sky over time, the EQ-1 mount is equipped with handy slow-motion controls so you can slowly "track" an object by twisting the slow-motion control knob to keep what you're looking at centered in the eyepiece. This lets you enjoy the view as long as you like without having to repeatedly re-aim the telescope. You can even add an optional electronic motor drive (sold separately) to the StarBlast II 4.5 EQ so it will track objects automatically once you've centered what you want to look at in the telescope eyepiece. The adjustable-height aluminum tripod allows you to set the StarBlast II 4.5 Equatorial Reflector up for comfortable views, while remaining lightweight so the entire assembled telescope is easy to transport.

    If you're looking for an exceptional beginner telescope to nurture interest in space and science, or if you're seeking a second telescope that's more portable than your big "light bucket", then pick up an Orion StarBlast II 4.5 EQ. Trust us, you'll have a blast!
