Aladin is a free interactive sky atlas available online or for download to your PC.
It allows users to load astronomical images, access data such as celestial coordinates, magnitude, and color indices, and perform measurements.
Users can compare their images with those from astronomy image databases simultaneously.
The software aids in both observation planning and image analysis, enabling users to adjust the field of view, check light intensity, and track objects like asteroids and comets.
Aladin also integrates with the Simbad database, VizieR service, and other archives to provide comprehensive information on astronomical objects.
The atlas is available for various operating systems.
