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.

The 4.5" aperture reflector telescope's short focal length serves up a generous chunk of sky in the eyepiece, making it easy for beginners to find celestial objects to study. This tripod-mounted version of the StarBlast 4.5 reflector offers an even more pronounced wide-field viewing experience compared to its tabletop counterpart, as we've upgraded the telescope eyepieces to include two from the Orion Expanse series - a 15mm and 6mm - which have a large 66 apparent field of view. Observations of everything from the Moon to Messier objects appear exceptionally sharp and rich in contrast through this petite reflector telescope. The included 15mm Expanse eyepiece provides 30x power magnification, while the 6mm Expanse eyepiece bumps up the power all the way to 75x magnification. The 15mm is a great eyepiece to begin observing sessions with, since it provides a large window of night sky for you to view. Once you've found an object you'd like to inspect more closely, swap out the 15mm Expanse with the 6mm eyepiece and enjoy a significantly more powerful view.

The Beginner Barlow Kit that comes with this value-packed telescope setup is a great combination of accessories for anyone beginning a hobby of amateur astronomy and includes the powerful Orion Shorty 2x Barlow Lens, as well as the useful Orion Beginning Stargazers Toolkit.

Use the included Orion Shorty 2x Barlow Lens to double the magnifying power of included eyepieces.

A 2-power (2x) Barlow lens is an extremely versatile telescope accessory that doubles the magnification of any eyepiece installed. Using the included Shorty 2x Barlow with the 6mm eyepiece in the StarBlast 4.5 EQ bumps its viewing power from 75x to 150x, and boosts the 15mm eyepiece's magnification from 30x to 60x when used with the 4.5" reflector. What's more, you can use the compact Shorty 2x Barlow with any other 1.25" eyepieces you already have, or any you purchase in the future.

The Orion MoonMap 260 makes it easy to learn about the Moon's craters, spacecraft landing sites, and more!

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 whole family will enjoy looking at the Moon with the StarBlast 4.5 EQ telescope, then discovering the names of the craters and other features you've seen in the telescope.

The Orion Star Target planisphere is a useful star chart wheel for any day of the year.

This circular star map lets you dial-in the month and day you're observing the sky, so you can see exactly which constellations and stars will be visible if skies are clear. Using the Orion Star Target is a great way for starters to plan their first stargazing sessions with the StarBlast 4.5 EQ reflector, since you'll know just where to point the telescope!

The useful Discover the Stars guidebook will introduce you to the wonders of the night sky.

This gets our vote as the best guidebook for beginning stargazers. The heart of the book is two sections of big, two-color sky charts. The first section features 12 charts that show the entire visible sky each month, accompanied by text that points out each month's sky attractions and constellation mythology. The second section comprises 23 charts of smaller regions of the sky, which highlight objects observable with small instruments. Softbound, 119 pages.

Use the included RedBeam Mini LED flashlight to see in the dark without disrupting your dark-adapted vision.

You don't need a big flashlight to read star maps or see inside your accessory case at night. The included 2.5"-long Orion RedBeam Mini Flashlight does the job perfectly, emitting night-vision friendly red LED light. Red light won't disrupt your eyes' dark-adapted vision, so this flashlight lets you check charts and accessories while keeping your eyes primed for viewing celestial gems through the StarBlast 4.5 EQ telescope. Includes batteries and a handy key-ring.
