I am completely dedicated to SkyMap Pro
as my astronomy charting software, but it does cost the odd bob or two. Cartes du Ceil
is a free program which work rather nicely (after you sort out what downloads where). However, if you have a JAVA enabled web browser, try out SkyView Cafe
. It's a little slow over dialup lines, and not as full featured as a commercial application, but it is free, configurable and works quite nicely indeed. Drop into the SkyView Cafe homepage
for more information.
