What’s Included in the Box

In the box, you’ll find everything you need for stargazing from the telescope tube itself to the two separate eyepieces. One eyepiece is 17 mm while the other is a 6 mm Orion Explorer II telescope eyepiece. It comes with an Altazimuth base, collimation cap, tube clamp, Orion EZ Finder II reflex sight and the Starry Night software.

Setting Up the Telescope

When you receive the telescope, there isn’t much that you have to do to assemble it. There’s a solid piece for the base that swivels, the two eyepieces, the EZ Finder and the telescope itself. To attach the EZ Finder II, all you need to do is remove the thumbscrews, place the finder onto the two attached posts and secure it with the screws.

The Orion StarBlast is one of the easiest telescopes to set up when it comes to the eyepieces, too. Within a few seconds, you’ll go from looking through one eyepiece to switching magnifications with the other eyepiece. This video can help you visualize the process if you’re better when seeing a process instead of reading it.

Red Dot Sight

The Orion telescope comes with an EZ Finder II red dot sight. It allows you to find objects in the sky much easier. It’s truly a telescope made for a beginner astronomer. To accurately find objects in the telescope, you could scan the night sky until you stumble across something that looks like the object you wanted.

You won’t know for sure when you’re a beginner, though. Align the telescope with the red dot on the object in the viewing window, turn the telescope in the right direction. Voila! You’ll have the object in the eyepiece. This makes it simpler for children to operate, too.


When you first set up the telescope, you’ll want to scan the night sky in a broader view before honing in on certain celestial objects. There’s a medium magnification eyepiece of 17 mm that will give you a broad view of the sky. When you’re ready to view certain objects at a higher magnification, you can switch to the 6 mm eyepiece that will give you a more powerful magnification.

Starry Night Special Edition Software

Included with the telescope is software that teaches your little astronomer how to find objects in the sky. It has so much useful information, and you can use the software to find out what objects will be visible on certain days of the year.

This makes planning your stargazing more productive. While time spent with the children is never wasted, you want them to be excited and see the stars and planets through the telescope. It’s never fun to disappoint the little ones.

Compact and Portable

This compact, portable telescope has a sturdy tabletop base and a handle that makes it a simple matter of placing it on the base to set up the telescope. When you want to take this bad boy camping with you, it’s easy to place this in a bag and place it in the trunk with other items. On your next camping trip, the fun doesn’t have to end because the stars come out in the sky. That’s when the delight and wonder really begins!
