Starpath Perpetual Almanac for Windows computers
Needless to say, we recommend a hard copy of the Nautical Almanac if you are relying upon celestial navigation underway, but if you have a computer onboard this simple program will provide a wonderful backup to a lost or out of date Almanac. It might also be of interest to those who do only periodic cel nav on land. Paper versions cost some $30 to $50 depending on source, so this perpetual data could be an economical alternative. [Save even more with a download delivery at $39 and no shipping. The download version is identical to the packaged CD]

It is extremely simple to use and provides all ephemeris data available in the paper editions, namely: GHA, Dec, SHA, SD, HP, magnitudes, sunrise, sunset, LAN, twilight times, moonrise, moonset, moon age and phase. We include sun, moon, 5 planets, and 270 stars, ie one more planet (Mercury) and many more stars than are in the nautical print version. In addition, we include Hc at LAN, bearing of sunrise and sunset (amplitudes), and the GHA of Aries midway between civil and nautical twilights for star planning.

Just enter a time and date from the convenient calendar selector, select your body, and get the data. You can get individual data, or ask for a print out of sequential data for the time interval and number of points you wish. You can also choose to save this data to a file, rather than hardcopy print.

Ideal for historians as the data are accurate back to 1590. We have checked numerous historic sights including many from Lewis and Clark, etc.
