NAPA - Star Map is an astronomy and planetarium app developed by the National Astronomical Research Institute of Thailand (NARIT). This app serves as a guide to the night sky, helping users identify stars, constellations, planets, and other deep sky objects. By simply pointing your phone at the sky, NAPA provides real-time information about celestial objects.

One of the key features of NAPA is its star map functionality. Users can adjust the observation time to plan future observations and familiarize themselves with the patterns of the night sky. The app also allows users to locate deep sky objects that can be seen with binoculars or a small telescope.

NAPA aims to make astronomy accessible to everyone, with a particular focus on assisting schoolteachers and public outreach personnel. The app is free to use, but there is a pro version coming soon that will offer additional features to enhance the user experience.

Some notable features of NAPA include the ability to display celestial objects based on the position of your smart device, the option to drag the screen to turn the app into a star map, and the simulation of planet positions at any given time. Users can also select specific constellations, planets, or deep sky objects to locate their positions in the sky.

With its photo-realistic simulation of star appearance using real astrophysical models and real images of deep sky objects, NAPA - Star Map is a valuable tool for both amateur and professional astronomers alike.
