Please Note

Orion has made the difficult decision to close our warehouse facility in the Netherlands. With the continuing supply chain/logistics challenges and slowness in the economy we have found that it is not economically feasible to maintain operations in the UK and Europe.

We have therefore stopped taking orders on this website. We apologize for any inconvenience.

We will continue to have Orion dealers in Europe to meet the needs of Orion consumers. We will also continue to honor the 30-Day product return period as well as honoring the Orion warranty for purchases made in the UK and Europe.

Our US-based Customer Service Representatives are here to help. Contact them via email at support@telescope.com or in the United Kingdom, via phone at 0-800-041-8146 (Monday-Friday between the hours of 1300 and 2400 GMT).

Item #  09798u

This 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 with a precise equatorial mount 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.

Start each stargazing session with the 15mm Expanse eyepiece for medium-power views.

When inserted in the StarBlast 4.5 EQ reflector telescope, the included 15mm Orion Expanse eyepiece provides a 30x view with a wide, 66° apparent field of view. The 15mm Expanse ocular is a great eyepiece to use when you first begin your telescopic observations each night, since it provides a large window of night sky for you to view. You'll get wonderful views of deep space objects like star clusters and cloudy nebulas.

Increase magnification for more powerful views with the 6mm Expanse eyepiece.

After you've scanned the skies with the 15mm Expanse in the StarBlast 4.5 EQ, take a much closer look at interesting objects by swapping out the 15mm eyepiece with 6mm Expanse to boost magnification all the way up to 75x. The more powerful view provided by the 6mm focal length eyepiece makes it easier to discern 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 easy.

The Orion EZ Finder II reflex sight makes it easy to aim the StarBlast 4.5 Equatorial 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 wish to view through the telescope. With the EZ Finder II reflex sight, starhopping around the sky is a breeze for anyone in the family!

Learn about the night sky with the included Starry Night Special Edition software.

Explore starry skies anytime - even when it's cloudy! The Orion StarBlast 4.5 EQ telescope includes a FREE Special Edition of Starry Night astronomy software. With realistic sky simulations and a many useful features including telescope control, the user-friendly Starry Night Special Edition software will help you plan your observations and understand what you see. Requires PC running Windows 7, 8 or 10. Requires Macintosh running OS X 10.4 or higher.

With the included Orion EQ-1 equatorial telescope mount, you will be able to keep your target object centered in the telescope eyepiece with only an occasional tweak of one slow-motion cable. The EQ-1, like all equatorial telescope mounts, orients the attached StarBlast 4.5" reflector telescope on two axes of motion (right ascension and declination), allowing you to easily track celestial objects as they appear to move across the night sky. Thanks to this design, it's easy for anyone in the family to manually track a celestial object using slow-motion control cables. You can even add an optional electronic motor drive (sold separately) to the EQ-1 equatorial mount so it can track objects automatically once you've centered the object in the telescope eyepiece. The adjustable-height aluminum tripod allows you to set the StarBlast 4.5 Equatorial Reflector up for comfortable views, while remaining lightweight so the entire assembled telescope is easy to transport to and from your favorite stargazing location.

If you're looking for an exceptional beginner telescope on a stable mount with slow-motion tracking control, or if you're seeking a second telescope that's more portable than your big "light bucket", then get an Orion StarBlast 4.5 Equatorial Reflector Telescope. Trust us, you'll have a blast!
