General graphics applications


Gimp


http://www.gimp.org/

The Gimp is a graphics application, pretty much a standard and either featuring as part of most distributions, or downloadable as a package within the repositories. It is part of Gnome desktop, and is to Linux what Adobe Photoshop Elements is to Windows. Its functionality can be extended with plug-ins in a similar way to Adobe Photoshop, but does not feature a comprehensive suite for astronomical image processing like Noel Carboni's Actions.

Gimp Astronomy Plugins


There are several available from different sources. All are limited because of Gimp's 8-bit colour depth restriction.

This contains six plugins for deep space image processing.

I highly reccomend this software.
