'Nebulosity' (Windows and OS X) is designed to be a powerful, but simple to use capture and processing application for a wide range of astronomy CCD cameras. Many cameras are supported for capture and images from just about anything can be processed including png, tiff, jpeg and many other file formats.
Download it for free.
RegiStax, free image processing software allows you to stack a series of images of an astronomical object and process them to produce truely stunning finished work. The best bit is, it's free! Check out the following Youtube videos:
IRIS Astronomical images processing software
Iris provides many powerful functions of
image processing for digital astronomical
images. It is particularly good when used with images captured
by CCD or DSLR cameras.
|Satscape is a free/donation-ware
Satellite tracking program that uses mathematical equations
to accurately predict the position of any satellite in orbit
around the earth, or predict to the nearest second when a satellite
will pass over your location. You don't need a huge tracking
radar in your back garden, just this program and a computer.
|Stellarium is a free
open source planetarium for your computer. It shows a realistic
sky in 3D, just like what you see with the naked eye, binoculars
or a telescope.
It is being used in planetarium projectors. Just set your coordinates
desktop planetarium software includes 50 guided tours to get

|AstroGrav is an astronomy software program that allows
you to simulate how astronomical objects move and interact
under the force of gravity. It features superb interactive
3D graphics which allow you to move around within a many-body
astronomical system, while watching how it evolves with the
passage of time.
