Star Atlas 0.6b1
This is an Educational Game
Mactivity's CD-ROM nr 10 advice: This application did
run on a b/w 68030 processor under System 7.1. It was
also tested on a big ColorScreen of a PowerMacintosh
running System 7.1.2. The game was also tested on a
Quadra with 68040 processor and a 13 inch Color Screen
and System 7.1 by Mactivity.
This program draws a map of a region of the sky. Unlike
the preceding application StarChart (*), it conforms
to the Apple standard menu system with reverted black
menu bar. (Otherwise you will find the white menu
very disturbing...) It runs with MultiFinder. I confirmed
it runs on MacPlus, SE, SE/30 and II with System 6.0.2
or later. To run this program, an accompanied data
file "star.catalog" should be put in the
same folder. This data file is converted from David
Palmer's "stars.cart", which he claims as
public domain and contains the position, magnitude,
name and color of 1573 stars. To change the center
position of the Atlas, use R.A. (Right Ascension) and
Decl. (Declination) menus. You can also change the
center position by clicking a portion of the Star Atlas
window. Zoom menu changes the scale of the Atlas.
Star names can be displayed on the screen by checking
"Display star names brigher than..." option
in the "Preference..." dialog box. They
are shown as abbreviated composites of their Greek
prefixes and the constellation names. For example,
"alpCMA" is CMA alpha (Sirius, aka Dog Star),
and "betORI" is ORI beta (Rigel, Orion).
Window size may be changed by dragging the grow icon
at the lower right corner of the Atlas window although
the grow icon itself is not visible. You will notice
a change in the shape of mouse cursor from cross to
arrow when you are in the grow box. You can also move
the window by dragging a pixel-width white line just
below the menu bar. Clicking in the zoom box in the
upper right corner of the Atlas window will put the
window back to the original position. Drawing a map
takes time on old machines like Plus or SE (typically
30 sec for poloar maps, namely Decl. = +/-90o and +/-60o,
10 sec for other maps), so please be patient!
