UNISTELLAR App
The UNISTELLAR App turns an Android or iOS smartphone or tablet into a controller for a UNISTELLAR telescope.
What UNISTELLAR App is
The UNISTELLAR App turns an Android or iOS smartphone or tablet into a controller for a UNISTELLAR telescope. Its Galactic Guide lists more than 5,000 celestial objects and suggests viewing targets based on location and time of night. Users can select objects for the telescope to point at and track, or move through the sky with an on-screen joystick. The app provides information such as an object's distance, magnitude, age, and type, and lets users capture, adjust, and share images. It also offers citizen-science activities with experts, including NASA and SETI. The telescope connects over Wi-Fi and Bluetooth, and creates its own Wi-Fi network, so operating it does not require internet access. Minimum requirements are Android 10 or iOS 18, 2 GB RAM, and 500 MB of storage; 1 GB is preferable. FireOS, Kindle, Chromebook, Fairphone Open, Huawei Harmony OS, and desktop computers are unsupported. The app is free. Its privacy policy says it is linked to the telescope model and serial number and that usage information, including activation details, responsiveness, and errors, is collected.
