Software

Software related to astronomy. This includes desktop planetarium and sky charting software, astronomy databases and observing utilities, simulation software, image processing and data analysis, education and multimedia software, and software reviews.

Please note that, even though only software with dedicated web pages is included in this directory, there are many programs (mainly shareware/freeware) that have no web sites dedicated to them and are only available from a number of online software repositories (links to such repositories are included in this directory).

Sites in Software
