星座早見 is an iOS app that brings the Nagoya City Science Museum's original star chart to your fingertips. This app allows you to explore the night sky at any time and from anywhere. Upon launching the app, you are greeted with a real-time representation of the sky. If you want to view the sky at a different time, simply swipe or rotate the chart with your finger. The app is designed to be user-friendly, with easy-to-use pinch gestures for zooming in and out. It also features a night mode, making it easier to view in low-light conditions.

One of the standout features of 星座早見 is its ability to display the positions of planets for the selected night, something that is not possible with printed star charts. The app calculates and displays the positions of the five visible planets and the moon, allowing users to easily locate them in the night sky.

Whether you're a beginner or an astronomy enthusiast, 星座早見 is a great companion for stargazing. Its intuitive interface, convenient features, and accurate celestial information make it a must-have app for anyone interested in exploring the wonders of the night sky.

Please note that this app is developed by IMAGE FACTORY CO. LTD. and is available for free on the iPhone platform.
