Hello and welcome!

TelescopeTrader (or TT for short!) is a 100% user-supported surplus astronomy gear exchange. TT is entirely supported by our private astronomy community. What that means is that the only ads you’ll see here on TT are ads from our members and community business sponsors. We do not display any large corporate 3rd-party advertising (e.g. Google, Bing, etc.), nor do we sell your data. Types of listings allowed include used telescopes, telescope accessories, telescope eyepieces, telescope mounts, telescope parts, and astrophotography gear. If you’d like to become a telescope mentor, we welcome these types of posts in our services category.

Who we are

My name is Michael, a professional web developer and amateur astrophotography nerd. I created TT, with the help of my eldest son, to help more people discover and learn about backyard astronomy and astrophotography. TT is a family-owned business located near Tucson, Arizona and has been operating since 2017. TelescopeTrader.com is hosted, managed, and maintained via support from our member community through affordable annual memberships and sponsor advertising. Please reach out to me with any suggestions or feedback here.

Our mission and values

We aim to be the Internet’s best astronomy gear exchange and help support the growth of amateur astronomy and astrophotography in local communities. Through past and present involvement with astronomy clubs and related organizations like The International Dark-Sky Association, Planetary Science Institute, and SETI we are encouraging people of all ages to get involved with astronomy and astrophotography. Also, we support environmental sustainability by helping encourage recycling of used astronomy equipment, telescopes, and astrophotography gear.

Why sell used astronomy equipment here

If you are selling used telescope equipment, one important thing to note about TT is that it reaches a broad audience of people – many are just getting into astronomy. They’re often searching for inexpensive telescopes, cameras, and so forth. So, it’s a really great platform to get your used gear ads or service ads in front of a diverse group of astronomy enthusiasts. Also, please keep in mind that we never sell your personal info or run any large corporate advertising. We are a private astronomy community and an annual or one-time membership is required.
