Our compact, performance-packed Orion StarBlast II 4.5 EQ Reflector telescope is a favorite of both beginners and expert astronomers alike. It combines the much-heralded Orion StarBlast II 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. Observations of everything from the Moon to Messier objects appear exceptionally sharp and rich in contrast through this petite reflector telescope. The included 25mm Sirius Plossl eyepiece provides 18x power magnification, while the 10mm Sirius Plossl eyepiece bumps up the power to 45x magnification. The 25mm 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 25mm Sirius Plossl with the 10mm eyepiece and enjoy a significantly more powerful view.

The accessories included in this value-packed Telescope Kit have been selected to enhance stargazing experiences for anyone beginning a hobby of amateur astronomy.

Barlow

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 10mm eyepiece in the StarBlast II 4.5 EQ bumps its viewing power from 45x to 90x, and boosts the 25mm eyepiece's magnification from 18x to 36x 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.

Moonmap

The Orion MoonMap 260 makes it easy to locate and learn about interesting features on the Moon.

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 II 4.5 EQ telescope, then discovering the names of the craters and other features you've seen in the telescope.

star target

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 II 4.5 EQ reflector, since you'll know just where to point the telescope.

OTOG book

The Orion Telescope Observer's Guide book will introduce you to the wonders of the night sky.

This book will help you explore amazing celestial objects including planetary, emission and reflection nebulas; double and multiple stars; open and globular star clusters, the Andromeda Galaxy, and more. With a full page of information dedicated to each interesting object, author Richard J. Bartlett leads you on a detailed tour of the night sky as he describes over 60 fascinating astronomical objects that can easily be seen with a small telescope.

flashlight

Use the RedBeam Mini LED flashlight to see in the dark without disrupting 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 II 4.5 EQ telescope. Includes batteries and a handy key-ring.
