I tried the electric astrolabe and I decided to use it in a course dedicated to people that teach Astronomy in middle and high italian schools. I would like to thank James E. Morrison, Janus.
Some years ago I wrote a similar program in alto-azimutal coordinates. A window coloured version is under construction. If you want you can download the old B&W version at this addrress: http://www.unisi.it/ateneo/dipart/fisica/luciana/software.htm There are two packages: Astronomia 1 Astronomia 2 try both of them!! A presentation of the new version is at: http://www.arcetri.astro.it/CDAs/software/planetario.html Pay attention: until now, both version are in italian, sorry. Piero Ranfagni
