StarCalc is a compact planetarium program that provides the opportunity to explore the starry sky and the location of objects on specific dates and from a particular angle. You will be able to see the entire celestial hemisphere or increase any part of it arbitrarily. The program's capabilities include not only zooming in and out, but also zooming in and out, and you can rotate the image at different angles, save it on disk, and even print it out if necessary. This program provides you with several interfaces, such as Horizon, Horizontal Grid, Equatorial Grid, Constellation Boundaries, Constellation Lines, Constellation Names, Own Star Names, Bright Star Catalogue, Galaxies, Nebulae, Cluster Names, Sun, Moon, and Planets and Satellites. StarCalc has a simple and accessible interface, most of the operations are performed with the help of "mouse" or "hot keys".
