StarHi is a practical astronomy app that helps you to explore the starry sky. You can mount your phone on a telescope and use the app to help the telescope accurately locate celestial bodies with some simple settings. The app utilizes your phone's time, location, and sensor information to determine the positions of the moon, planets, stars, deep space objects, and constellations in the night sky. Additionally, it provides basic information about various celestial bodies. Main Features: 1. Ensures that the starry sky displayed on the mobile phone matches what is seen through the telescope. 2. Displays the direction in which the telescope is pointing. 3. Simulates the visual fields observed by telescopes of different magnifications and structures. 4. Helps novice astronomers identify and locate celestial objects in the vast night sky. 5. Simulates the starry sky in real-time or at a time and place set by the user. StarHi is a new astronomical application. Compared to other star-finding software, StarHi uses a new algorithm that makes the starry sky displayed on the phone screen consistent with what is seen through the telescope with simple settings. Users can use the app's celestial body information and screen icons to align the telescope with the celestial body they want to observe. Download StarHi now and start your celestial adventure.
