- Galileo 1.0 for the Psion Series 5
- ==================================
-
- Galileo plots the positions of the Galilean moons of
- Jupiter, given the date and time of observation. The
- moons can be shown as they would appear through binoculars
- (and the naked eye if you're Superman!) or through an
- astronomical telescope (east/west reversed).
-
- It uses a simplified algorithm that only calculates the
- east/west positions of the moons - it was really written
- so I could check I was seeing what I thought I was seeing
- through my oh so wonderful Tasco binoculars...
-
- Installation
- ------------
- Unzip the archive, and place the two files galileo.app and
- galileo.aif into the directory \System\Apps\Galileo. The
- program should work when installed either on the internal
- RAM drive or a Compact Flash card, although as I haven't got
- one I can't confirm that. Galileo should now appear on your
- Extras bar (no flashy icon I'm afraid, at least not yet).
-
- Usage
- -----
- Run Galileo, and it will ask you for the date and time of
- the observation. Input the time as local time and the
- number of hours your time zone is ahead of Greenwich Mean
- Time. Finally select whether you want a binocular or telescope
- view, and press Enter or select the OK button. Galileo will
- then plot the positions of the four moons, both in plan view
- and the view you would have from Earth. Press any key to return
- to the entry dialog, from where you can have another go or
- press Escape to exit.
-
- Ob. disclaimer
- --------------
- I have done my best to ensure that Galileo works and I can't
- imagine it trashing your machine, but don't blame me if spooky
- things happen after you install it. It's probably the pixies...
-
- Galileo is freeware, copyright Andrew Hedges 1997.

- ftp://ftp.doc.ic.ac.uk/Mirrors/ftp.cdrom.com/pub/simtelnet/msdos/astronmy/galsat53.zip)
