With all the help from major Linux distributions such as SuSE, Redhat and many others, Linux based systems are becoming easier to use. However, there is still some need of understanding of basic UNIX skills to make the most of Linux. Thus, this HOWTO will assume that the reader has at least a basic knowledge of using a UNIX system including the ability to compile and install programs.
A few resources we have found useful over the years include:
"A Practical Guide to the UNIX System", Mark G. Sobel
"Advanced Programming in the UNIX Environment", the late W. Richard Stevens
"Running LINUX", Matt Welsh et al.
"LINUX Device Drivers", Alessandro Rubini
Similarly, this is not a tutorial or reference for astronomy principles or astronomical instrumentation. Astronomy is perhaps the grandest of all sciences, employing widely disparate disciplines in a bold attempt to understand nothing less than the universe itself. Your interests will lead in many directions. A few references we have used include:
"Explanatory Supplement to the Astronomical Almanac", P. Kenneth Seidelmann
"Astronomy with your Personal Computer", Peter Duffett-Smith
"Astronomy on the Personal Computer", Oliver Montenbruck et al
"Textbook on Spherical Astronomy", W. M. Smart
"The Astronomy and Astrophysics Encyclopedia", Stephen P. Maran, ed.
The authors define the scope of this HOWTO as primarily an index to Linux tools applicable in some fashion to the pursuit of Astronomy. It is NOT our intention to list WWW astronomy references in general. Our own interests tend more towards the technology than the pure science and so we welcome contributions from others who have found Linux tools which contribute in other ways to Astronomy. Please contact us at the address above.

Here are some links to collections and other indexes of Linux astronomy software.
AstroMake is a utility intended to make installations of some common astronomical packages (in binary form) easy.
The linuxastro mailing list also contains a list of applications and packages. For more information, see linuxastro.
If the above does not appeal to your needs, these links may help:
Here is discussion of programs which run on Linux for use in finding objects, natural and man-made, in the sky.
XEphem has been the pet project of one of us (Downey) for the past 15-odd years. It has grown to become one of the more capable interactive tools for the computation of astronomical ephemerides.
XSky is by Terry R. Friedrichsen, firstname.lastname@example.org. XSky is essentially an interactive sky atlas.
KStars is a Desktop Planetarium for KDE.
Skymap is an astronomical mapping program written in Fortran and C for unix workstations by Doug Mink of the Smithsonian Astrophysical Observatory Telescope Data Center.
Xplns reproduces real starry sky on your display of X Window System.
Nightfall is an astronomy application for fun, education, and science. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves and radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system.
NOVA free Integrated Observational Environment for astronomers.
The advance of palm computers has taken hold. Linux has made its way to this realm.
Clear Sky Institute brings us the Personal Sky Chart for the Sharp Zaurus PDA.
Programs that classify themselves as simulators.
Astronomical Information Processing System (AIPS) is the heavy iron used by professional astronomers. AIPS++ is the place to find out more, but note that AIPS Classic also exists and is actively maintained.
Good ol' GNU Image Manipulation Program (GIMP) is a fine program to use for processing of digital images of all kinds and can prove useful for astro images as well.
A surprising number of applications deal with just the Sun and Moon.
This section discusses bits and pieces of software that can be used to form the basis for specialized projects.
Astrophysics Source Code Library is a collection of links to numerical astrophysical process models.
Astronomy and numerical software source codes is a collection of C codes related to astronomy.
CCD Astronomy on Linux. A library of routines that help control SBIG cameras.
Orbit - Be a space fighter pilot in Windows or Linux.
Every list needs a miscellaneous section, and this is it for Software.
IRAF is a gigantic but exceptionally capable astronomical analysis system, shepherded over the past 20-odd years by Doug Tody formally at NOAO. It has accumulated innumerable authoritative contributions from leading astronomers in all areas of astronomical data analysis. If you have a serious interest in astronomical data reduction and significant time to invest, this system will reward you mightily.
Xplanet Very realistic rendering program for Earth and other planets and moons. Uses X Windows and OpenGL.
StarPlot A 3-Dimensional Star Chart Viewer for Linux. Uses C++ and Gtk+.
I know we said we would not start listing Web sites, but here are a few links to sites which offer fully operational tools running online that we feel are especially useful or interesting, from a browser on any platform.
Clear Sky Clock will show at a glance when we might expect clear and dark skies for one particular observing site.
The Simbad astronomical database provides basic data, cross-identifications and bibliography for astronomical objects outside the solar system.
Much effort exists to allow access to Astronomical image file type such as FITS from any web browser. Here are some pointers.
The folks at harvard have a list of Image Servers and Image Browsers.
The yearly Astronomical Data Analysis Software and Systems, ADAAS, Conference Series provides a forum for scientists and computer specialists concerned with algorithms, software and operating systems in the acquisition, reduction and analysis of astronomical data. The program includes invited talks, contributed papers and poster sessions as well as user group meetings and special interest meetings ("BOFs''). All these activities aim to encourage communication between software specialists and users, and also to stimulate further development of astronomical software and systems.
The linuxastro mailing list, email@example.com, is for people who are interested in porting astronomical software to linux. For more information, see linuxastro.
More folks are using Linux to control equipment. Users range from amateur astronomers in the field to professional observatories.
KTelescope is a robust Client/Server control library for Meade's LX200 based telescopes. Is uses the Instrument Neutral Distributed Interface (INDI) protocol.
XEphem has the capability to communicate with a telescope control daemon process.
Apogee Instruments Inc supports their line of professional CCD cameras under Linux.
Finger Lates Instrumentation Manufacturer of CCD cameras and filter wheels and include drivers for Linux.
SBIG offers some assistance with operating their ST7 and ST8 CCD cameras under Linux.
CCD Astronomy on Linux These pages describe a number of facets of using astronomical CCD cameras for image acquisition and processing under Linux.
Gccd is a gnome-based CCD camera and filter wheel control program.
You need to know what you're doing with Linux and installing programs, but help is available for some programs. Here are some ways to make life easier.
AstroMake is a utility intended to make installations of some common astronomical packages (in binary form) easy.
XEphem requires several elements to exist on your machine. Life is much simpler with the CDROM version of the program as it contains an installation script which loads the appropriate precompiled binary for most systems and places all auxiliary files to the correct spots. See XEphem CDROM
Here is a list of astronomy projects using Linux in whole or in part of their instrumentation:
