I like Planetarium, too, but it does not run on the Pocket PC platform,
which is the type of device the original poster has.

True but putting in a plug for a good Palm based program is a service for who
may have just read the header.

Of course your own PleiadAtlas is another powerful Palm program.

Both Planetarium ($24) and PleiadAtlas ($10) can be downloaded from the net as
shareware that is fully functional. I registered both and use both..
