Unravel the Night Sky from Any Location
Our **Planisphere** is an innovative and intuitive tool designed to make stargazing and celestial navigation accessible to high school students and astronomy enthusiasts alike. Unlike traditional planispheres, its unique design integrates Earth's geography, allowing for a truly personalized view of the cosmos.
How It Works:
- **Rotating Star Chart Overlay:** The instrument features a primary circular overlay, a **star chart**, which shows the constellations and celestial coordinates.
- **Stereographic Earth Map Base:** Uniquely, positioned beneath this star chart is a **circular stereographic Earth map**. This map shows landmasses and geographical longitudes.
- **Dynamic Alignment:** Both the star chart and the Earth map are connected at their centers, allowing them to **rotate freely** around a common axis. To see the sky from any location on Earth, simply rotate the star chart and the Earth map until a specific **Right Ascension** on the star chart aligns with your desired **Earth longitude** on the stereographic map.
