Solun' - The Pocket Planetarium

Zenith star chart display. (Sony Ericsson P800)


Solun' is a small planetarium application designed for use on many platforms that have a Java runtime environment, including PersonalJava and Personal Profile.

Paying particular attention to the needs of smaller devices, this is my attempt to combine the best features of the popular Solun for Psion machines and the unfinished Solun for RISC OS with more accurate astronomical calculations.

Solun' is copyright software, released under a "Charityware" license. It is free to use but if you like it you may wish to make a donation to an environmental or humanitarian charity of your choice.
