Welcome to probably the best all round astronomy
program for the S.T.
The Astrolab program on this disc is version 0.7 and
contains many improvements over the 0.6 version. Not
least of these is the fact that is now runs on any ST
including the 520 and that all the drag of converting
the star data files (a 20 minute task and requiring ram
disks and one meg memories) is avoided. The program
is now ready to load and run.
To start just click on ASTROLAB.PRG. At the bell
press return and you'll reach the desktop. Select
"File" and click on DATEN (Ersetzen). At the file
selector box choose one of the three data files (the
figures refer to the limiting magnitude). When it has
loaded click on the right button and you are presented
with the standard star field. To add more stars click
on the right button to return to the desktop, select
file again, then DATEN (and this time Anfugen - which
means merge). You can load all three data files like
this which gives you a spectacular stellar view. You
can always control the number of stars on screen by
altering the magnitude limit with the "+" and "-" keys
on the numeric keypad. You'll find that the numbers
also change the field of view.
Clicking on the figures in the status line at the top
of the screen allows you to change all the
settings. From the left these are type of projection,
Bildw = Angle of view in degrees (255 to 6); L =
longitude (ö means east, w is west); Br = latitude (n
or s); Azimut = direction of view around horizon in 360
degrees (north is 0); Höhe = angle of vertical view
(+90 means you are looking straight up,-90 gives the
view view under yuour feet); zeit = time and of course
the date.
There is much more, so attached is a brief translation
of the other terms used.
Ekliptic = Ecliptic (yes, really)
Himmelsquä = Celestial equator
Horizont = Horizon
Raster = grid lines (as in RA and dec)+ means
fine, - is coarse.
Stauszeille = Status line
Sternbilder = Constellation outlines.
Tierkris = Signs of the zodiac.
Sternnamen = Star names.
Mauslock = sets higher rate for data change in
status line.
HÖheblock = sets horizon low on screen.
Mischen = holds star images so that trails are
produced under time movement.
Reverse = Black or white background.
Präzession = adds computation for precession when
plotting star positions,.
VoreinstellÜng= Window to enter details, time date
position, etc.
Finally; many of the ST's facilities work (rubber
banding with the mouse to select a screen view,
clicking with both mouse buttons - generally the left
advances data, the right button reverses it) Several
keys are "live" particularly the functions keys.
Remember if you are watching the skies wheel about they
move faster with the number of stars cut down, so press
the "-" numeric key while getting to where you want to
go and then put them all back with the "+".
