"BEST EVER $200 SCOPE?" That's what Sky and Telescope magazine asks about the OneSky on the cover of its February 2014 issue. Inside, a review titled "One Telescope for Everyone?" describes the OneSky as "one of those rare exceptions" that "gets all the important stuff right." Calling it "the best bang-for-buck beginner's scope", it also recommends the OneSky "for seasoned observers looking for a highly portable grab-and-go-scope".

Astronomers Without Borders' OneSky telescope
has been honored with awards from both
Sky and Telescope and Astronomy magazines!

Customer Julio Garcia says: Wow! I'm impressed! The telescope arrived today and I've just set it up. Even though it is the first time that I actually touch a telescope, I'm surprised how easy was the set it up and how nice I was able to see not only the Moon, but Jupiter and its moons! I want to say thank you for opening this amazing window for me and my family.

Customer John L., Groton, CT says: Have to start out saying the telescope is brilliant, its my first telescope and I am very excited about it!

Customer Tom F. says: I continue to use  the 5" scope, and continue to be impressed.  I am after messier and ngc galaxies and have not been disappointed. The ease of use and good optics are an unbeatable combination.

Customer Dick G., Dallas, TX "What a nice little scope! Takes higher power than the supplied ep's very well. Sets up easiily. Big time best buy. Lunar and planetary views really surprised me with their crispness."


The new OneSky telescope from Astronomers Without Borders – imported exclusively for AWB by Celestron* (see below) – features a 130mm paraboloidal f/5 mirror. With a truss tube that collapses to 14.5 inches in seconds and a total weight of just 14 pounds, performance and convenience are combined in one portable package.

A red dot finder, 1.25-inch helical focuser, and two eyepieces, SMA 10mm and 25mm, are included

The Vixen-style dovetail plate allows the optical tube to slide down for compact storage and transport. The optical tube can also be removed from its Dobsonian base and mounted on any compatible mount.

ALL profits go to Astronomers Without Borders global astronomy programs.

Celestron provides services including importing, warehousing, and shipping the AWB OneSky at their actual cost. AWB is thus able to to receive a generous profit of $94.99 from each sale while offering the OneSky at the very attractive retail price of $199.99.

Shipping FAQ

Why can't I buy the OneSky and have it shipped to my country?

We'd love to to ship the OneSky around the world, but a very similar model is sold by SkyWatcher in many other countries. Celestron and SkyWatcher are owned by the same parent company. If we sold the OneSky in those countries we would be competing with Celestron's sister company, and with an unfair advantage because of Celestron's support (see above).

Where can I get a OneSky in my country?

Look for a SkyWatcher dealer in your country and see if they have the Heritage 130. It's essentially the same telescope. SkyWatcher and Celestron are large supporters of AWB. By purchasing a Heritage 130 in other countries, you will continue to help them help us!

You're creating borders!

We like crossing borders. But we can't eliminate them. Sales of the OneSky support our borderless programs, accessible to everyone worldwide. While we can only raise funds with the OneSky in the US, we think it's worth doing to support our programs everywhere.

OneSky Technical FAQ

Q: What is the Allen bolt that comes with the OneSky in a small plastic bag?

A: The Allen bolt is an add-on that we requested so it's not included in the instruction manual. It threads into a hole in the rail that the telescope tube slides on and acts as a stop to keep the tube from sliding down too far when you stow it in the most compact configuration. Without it it's possible to slide the tube down to the point it impacts the base below it, which can leave dents in the base from the primary mirror collimation screws.

Q: The focuser has some slop in it that lets the eyepiece wobble just a little bit. Is there a remedy?

A: Teflon plumbing tape can be used on the threads to take up the slop in the threads. If it's used a lot, though, Teflon tape can wear out. Another option is wax. Just rubbing a lip balm stick on the threads will do the job. Grease can also be used but be careful not to let it get onto anything else. If cold weather is an issue in your area be sure to use a grease that doesn't stiffen up too much in the cold.

Q: What tripod should I buy for my OneSky?

A: The OneSky has an integrated mount that's meant to sit on a table or some other support. The telescope can't be mounted on a tripod with the mount, but a tripod isn't necessary, either. You do need to have something to set it on, though. The telescope tube can be removed and placed on a different telescope but not just a tripod alone. Getting a suitable mount for doing this would be expensive and you'd have a larger package to deal with. This isn't recommended unless you're doing something requiring tracking, such as astrophotography. Some people make a stool of sorts to set the OneSky on rather than using a table. There is nothing commercially available but there are plans for making one yourself at There is a great deal of information of all kinds in a long-running discussion of the OneSky and its use on the astronomy forum Cloudy Nights. You can ask questions there as well. See
