PyNOVAS allows you to calculate the position and movement of the sun, moon, planets, and stars with great precision using Python. It is based on the NOVAS software used by United States Naval Office (USNO) to produce the 'Astronomical Almanac' and 'MICA'. Ephemerides are supplied by the Jet Propulsion Laboratory (JPL). You can use this software for Celestial Navigation, and also as a basis for controlling astronomical equipment.
discord is a very simple Python module that allows for conversion from normal dates (via 'time.time', 'time.localtime', etc.) to Discordian dates. The module can either be used as a standalone command line application (which prints the current date in Discordian form) or as an extension module.
KAstrometry is an astrometry program for KDE. It is written in Python. It aims to be a good tool to make measurements of objects in space from images taken by CCD cameras. Such measurements might be used to find orbits of astroids or record the brightness of variable stars. One day, it should be able to record an object's position, detect stars, and find coordinates using star catalogs.
BOTEC is a simple but useful calculator that assists with astrophysical, orbital mechanics, and space navigation calculations. It is a "back-of-the-envelope calculator" rather than an industrial-strength calculator, although this may change in the future. It is primarily intended for people familiar with physics and Python, and as such is unlikely to be useful to the average end user. It includes solar system data, and all values are strictly in SI units.
Gregorian calendar 1582 is a small Python script to generate calendars for any year in the history greater or equal to one. The output format is the same as the Unix "cal" command. However, it supposes the Gregorian Reformation took place on October 4th, 1582, in contrast to the cal, which supposes the reformation took place on September 3rd, 1752.
AstroBuffer is a CCD astrophotography image manipulation application. It can open FITS and SBIG (st9) files. Contrast is adjustable to view different backgrounds and ranges of an image. It can scale, shift, rotate, and zoom in and out. Images can be aligned based on two star alignment, and can be summed, subtracted, averaged, and divided. RGB color images can be created from three images. Images can be saved as FITS or as any format that QT supports.
Hijra Islamic Calendar هجرة is an application for viewing the Islamic calendar (also known as Hijri calendar). It features a GUI with a tray applet. It includes both a high-level OOP library and a low-level library which can be used to implement other software that makes use of this type of calendar. It uses a special algorithm which gives much better precision than other known algorithms. It uses integer operations to avoid round off errors in floating point operations.
PAPFIP (Python And PGPLOT-based FITS Image Plotter) is a FITS image plotter based on the Python bindings to the pgplot graphics library. It is intended as a non-interactive (command line or script-driven) astronomical image plotter intended for the automated or repeated production of finalized publication-quality Postscipt files, rather than a method of inspecting or visualizing the data.
