SkyGlobe 2.5 is a fast, fun, and easy astronomy program. It uses either a CGA,
Hercules, EGA, or VGA graphics adapter, and can be configured to use as little
as 128K of memory. SkyGlobe 2.5 supports screen printouts on Epson-compatible,
Proprinter-compatible, or LaserJet-compatible printers. It displays 15,000
stars and the positions of the planets, as well as constellation lines. The
best feature of SkyGlobe is its blazing speed. It was programmed entirely in
assembly language, which allows it to generate up to several displays a second,
depending on computer system and screen complexity. Typical displays take less
than a second on even the slowest of PC-compatibles. All display features are
easily user-configurable, typically with a single keystroke. For instance, all
that is needed to Zoom in is for the user to press 'Z', or 'Shift-Z' to Zoom
out. It's that simple! Viewing direction is just as easy to change with the
use of the cursor keys. Viewing location can be chosen from a menu of over 230
locations worldwide. An Auto-Increment mode is available that lets the user
watch the movement of the stars for a night or a year. For educational users,
SkyGlobe 2.5 is the best way to watch the patterns of the planets, such as
retrograde motion, or to learn why we don't have eclipses every month. A few
keystrokes are sufficient to see when the moon is favorably, or unfavorably,
placed for a night of star-watching. But the best description of SkyGlobe 2.5
is to use it! Just make sure the files SKYGLOBE.COM and SKYGLOBE.DAT are in
the currently active directory, type SKYGLOBE, and let the fun begin!
