The PalmPilot software you want is CelestNav, and you can find it on
Palmgear.com.  I have been using it actively for over a year, it is
terrific software, well worth the modest price. Full almanac plus sight
reduction on any body you ever want to use, very easy to use. I
recommend it highly, there is a demo version and full tutorial at
www.mobilegeographics.com.

Subject: Re: Onboard electronic almananc

Here are some urls where I found an almanac, for the same reason of
having
it on board on the pc:
http://pollux.nss.nima.mil/pubs/  here you can find many publications
available for download also
http://www.geocities.com/andresruizgonzalez/  here you can find also a
free
software, very well done, for astro navigation
http://www.tecepe.com.br/scripts/AlmanacPagesISAPI.isa you choose the
day
and it gives you the pages for sun, moon, planets and stars valid for 3
days. Only problem you must be connected to internet.
If you have a Palm, go to www.palmgear.com and you'll find a program
that
will give you even your position putting in the sights, it's free for 30
days, then you have to buy it and its cost is around 49 usd.
