Starpath Perpetual Almanac

Item Code 60128

The same almanac program we use in our StarPilot software programs and home-study courses is now available as a stand-alone program. Just 200kb when installed. Quick, accurate, and easy to use. Note very basic system requirements below. It will run on any computer.

Needless to say, we recommend a hardcopy 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underway, but if you have a computer onboard this simple program will provide a wonderful backup to a lost or out of date book. It might also be of interest to those who do only periodic cel nav on land. Paper versions cost some $23 to $40 depending on edition per year, so this perpetual data could be an economical alternative.
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. The results have the same accuracy and precision as quoted in the print version of the Nautical Almanac.

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