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.
