Astronomy Software on the Internet
Missing in Action

These programs have been around for a while, but no longer have a web site for support (that I can find). Although some are old DOS programs, they still perform the tasks for which they were originally written. Most will run under later operating systems. If anyone has any information about these programs please contact me.
They can be downloaded from common download sites. If you are having problems finding them, drop me a line.

Astrodata v1

Download Available: Y
Filename: astros.zip  Size: 78 KB
Details: AstroData was developed for the budget-minded amateur astronomers. It was designed to clutter the screen with information necessary for the novice or serious amateur astronomer, and it is simply to use. There are good commercial astronomy programs, but the programs are too expensive! Today the computers are getting smaller, and because of their size, most amateur astronomer would like to take a notebook computer along with their telescope (yours truly). Taking a computer would eliminate the need for carrying along books, calculators, etc. The formulas were derived from the book: Practical Astronomy With Your Calculator 2nd Ed., Peter Duffett-Smith, Cambridge University Press ,Copyright 1979,1981

AstroSoft Computerized Ephemeris (ACE) v1.0

Download Available: Y
Filename: "ace1.zip, ace2.zip"  Size: "165 KB, 125 KB"
Details: ACE is a general-purpose astronomy software package consisting of three separate parts, each supporting a variety of astronomy-related applications. Part I of ACE (Astronomical Ephemeris) performs the most needed astronomical calculations, involving the sun, the moon, the planets, eclipses, astrophotography exposures, mean sidereal time and Julian Day, precession of coordinates, phases of the moon, equinoxes and solstices, Galilean satellites of Jupiter, perpetual calendar, and Polaris. It achieves an accuracy in calculations that is comparable to those contained in the ASTRONOMICAL ALMANAC and is more comprehensive and convenient, for astronomical observing purposes, than the FLOPPY ALMANAC. Part II of ACE (Solar System Data) provides, for all the planets and satellites of the solar system, orbital and physical data, as well as descriptive and observational data. Part III of ACE (Sky Catalog) provides data on over 2000 deep-sky objects, the entire Messier Catalog, 100 named objects, all bright stars to magnitude 2.00, and 100 prominent double stars, with detailed commentary on nearly 400 of these objects. Objects may be searched for on the basis of one criterion or by a combination of criteria.

FITS Imager 2000 v1.22

Download Available: Y
Filename: fi_setup.exe  Size: 2.3 MB
Details: The astronomical investigations (both professional and amateur) are nowadays based mostly on CCD images, containing deep sky objects. However, there is still lack of Windows applications that can process such images. FITS Imager is an astronomical application designed basically for photometry (brightness measuring) of stellar objects on the CCD frame. This application can load and display astronomical FITS format images, perform aperture photometry, create intensity profiles, etc. FITS Imager is excellent for detecting brightness variability of stars, for instance. In general, it is easy to learn and use, and might be useful to professional or amateur astronomers who deal with CCD images.

SkyBase 2000.0 Sky Chart was designed to use a disk database format so you can select the database with enough data to be useful but not so much as to be confusing. Current databases are constructed from the Yale Bright Star Catalog, the Smithsonian Astrophysical Observatory star catalog, the Messier objects, a collection of "best" NGC objects, and the Saguaro Astronomy Club catalog. As new data sources become available, new databases will be added.
