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).

Orion StarSeek Astronomy App

Orion's StarSeek is a powerful and easy-to-use astronomy app that is equally suited to beginning sky watchers on up to hard-core amateur astronomy enthusiasts and telescope users. Available for Apple (iOS) and Android devices, StarSeek lets anyone identify what's in the night sky simply by holding your phone or tablet up to the sky! But that's just the beginning. This feature-packed app lets you animate the stars and planets, look up upcoming sky events, plan and log observations, view hundreds of space images, and so much more. StarSeek includes 2.5 million stars, 31,000 deep sky objects, the Solar System's planets and moons, and over 4,000 updatable asteroids, comets, and satellites.

StarSeek 5 also enables wireless control of the complete line of Orion motorized GoTo and IntelliScope computerized "push to" telescopes/mounts using your smartphone or tablet! Telescope control requires the StarSeek Wireless (Wi-Fi) Telescope Controller module (sold separately) and the serial cable that came with your computerized telescope or mount. The StarSeek Wireless controller works with almost any brand of GoTo telescope or mount equipped with a standard USB or RS-232 serial interface. All you need is the RS-232 cable supplied by the manufacturer.

StarSeek 5 allows wired or wireless control of Orion's many computerized GoTo telescopes - from the portable StarSeeker IV line to the large-aperture SkyQuest series of GoTo Dobsonians - as well as Celestron, Meade, and other brands (see the StarSeek Telescope Control Compatibility page). It can point your GoTo or "Push-To" telescope anywhere in the sky, using your iPhone/iPad/iPod's built-in WiFi along with our StarSeek Wireless Telescope Controller module (sold separately). Plan observing sessions with Observing Lists, log your observations into them, and share them with friends. Once you try navigating the night sky with your iOS device and StarSeek, you'll never go back to controlling your telescope with its standard — and rather mundane by comparison — hand controller!
