Astroart is a software program for the processing and analysis of astronomical images. Its development began in 1999. The software is designed to work with images obtained by telescopes and astronomical cameras. Astroart includes tools for the calibration, alignment, and combination of night sky photographs. It supports a variety of file formats used in astrophotography. The application integrates functions for telescope and camera control. It offers algorithms for noise reduction and detail enhancement in images. Users can perform photometry and astrometry with precision. The interface is organized into modules for different tasks.
