Greetings,

The new version of XEphem, the serious astronomy software for all UNIX
systems including Mac OSX, version 3.6, will soon be announced. In the
mean time, we are offering our remaining inventory of version 3.5.2
CDs at a special closeout rate of $39.95, normally $59.95, plus
shipping and handling.

If you are new to XEphem this is a great way to give it a try because
if you buy version 3.5.2 at this closeout rate now, you will
automatically qualify for our usual 15% return-customer discount if
you wish to upgrade to 3.6 in the future.

Please visit http://www.xephem.com to learn all about XEphem and order
your copy today.

Thank you.
