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 4.5 Astro Reflector Telescope, then discovering the names of the craters and other features you've seen in the telescope.

Use the included Orion E-Series Moon Filter to enhance your viewing enjoyment of the Moon.

The Orion E-Series 1.25" 13% Transmission Moon Filter reduces glare and boosts contrast so you can see enjoy more detailed views of lunar surface features. It blocks excessively bright glare to provide a more comfortable view of the Moon's surface, the neutral density filter will not alter the natural color of the Moon and the eyepiece filter transmits only 13% of the incoming light, improving contrast and detail.

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 Astro Reflector Telescope, since you'll know just where to point the telescope!

Double the power of any 1.25" telescope eyepiece with the Orion Shorty Barlow Lens.

Doublet lens system is multi-coated for excellent transmission and the internal housing is baffled to eliminate unwanted reflections and increase contrast. Threaded for use with 1.25" Orion telescope eyepiece filters.

Detailed Observer's Guide highlights over 60 celestial objects to observe in a small telescope.

Packed with helpful hints and tips for exploring star clusters, multiple stars, nebulas, and even the Andromeda Galaxy. Useful resources for each object include a map, finder scope view, depiction of what you can expect to see in your telescope eyepiece, and more. A thorough guide to the night sky for stargazers of all skill levels from beginners to more experienced amateur astronomers. Softbound, 174 pages

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 4.5 Astro Reflector Telescope. Includes batteries and a handy key-ring.

The included Orion EZ Finder II red-dot sight makes aiming the telescope nice and easy.

Following a simple alignment procedure, you can use the EZ Finder II sight to accurately aim the StarBlast 4.5 Astro Reflector Telescope at objects in the sky like the Moon and bright planets. Once aligned with the telescope, just turn on the EZ Finder II and peer through the sight's small circular viewing window so you see the red dot, and move the telescope until the red dot is on the object you want to see. Look in the telescope eyepiece, and the object will be there!

Start stargazing with the 17mm Explorer II eyepiece for medium-power views.

The included 17mm Orion Explorer II eyepiece provides a 26-power view in the StarBlast 4.5 Reflector telescope. The 17mm Explorer II 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 for more powerful views with the 6mm Explorer II eyepiece.

After you've scanned the skies with the 17mm Explorer II in the StarBlast 4.5, take a much closer look at interesting objects by swapping out the 17mm ocular with 6mm Explorer II eyepiece to boost magnification from 26x all the way up to 75x. The more powerful view in the 6mm 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.

Dial-in celestial details with the smooth adjusting 1.25" rack-and-pinion focuser.

The Orion StarBlast 4.5 Astro Reflector telescope features a PTFE-lined rack-and-pinion 1.25" focuser built to accept any 1.25"-sized Orion eyepiece or accessory. The smooth focus control makes it easy to dial-in fine details when observing objects in the night sky, whether you're looking at a rocky lunar crater or a wispy nebula. The focuser features two knurled thumbscrews to secure inserted 1.25" eyepieces and accessories in-place.

Built-in base handle makes the StarBlast a great "grab-and-go" telescope

Thanks to the built-in carrying handle on the telescope's pre-assembled base, the StarBlast 4.5 Astro Reflector can be set up quickly and easily. With a total assembled weight of just 13 lbs., the StarBlast 4.5 is delightfully lightweight and sets up easily for fun nights full of astronomical adventures. Its compact size, light weight, and exquisite optics make the StarBlast 4.5 an excellent "grab-and-go" telescope that both beginners and experienced stargazers will appreciate night after night.

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

Budding backyard astronomers and families starting out in the hobby of stargazing can learn a ton of useful information with the included Special Edition Starry Night software ($69.90 value). You can use the software to see what stars, constellations, planets, and other cosmic objects will be visible on any day and at any time. This makes it fun and easy to plan family stargazing sessions since you'll know ahead of time which objects will be visible. Requires PC running Windows XP, Vista, 7, 8 or 10. Requires Macintosh running OS X 10.4 or higher.   

The extra accessories in this value-packed telescope kit will enhance your stargazing experiences.

Use the Shorty 2x Barlow lens to double the power of other 1.25" eyepieces. Use the included MoonMap 260 to properly identify lunar features seen through the telescope and the Moon Filter to reduce glare and enhance detail. Read the included Orion Telescope Observer's Guide book to learn how to locate and observe over sixty interesting objects to explore in the telescope. Use the Star Target Planisphere to see what constellations and objects will be visible on any day of the year. The RedBeam Mini flashlight makes it easy to refer to charts and books while observing, and it helps you see small parts and knobs without disrupting dark-adapted vision.
