Using the same standards of accuracy as published tables but with a catalogue extending beyond Barnard's Star; it can be used as a sight calculator, a definative astronomical reference or simply to print daily Nautical Almanac pages.
Multiple sights can be plotted/ combined while allowing for changes in course and/ or speed. Once an altitude and bearing has been entered, a list of potential bodies will be offered so that ambiguous sights will be immediately apparent.
The other data available is comprehensive e.g. a Star Chart, twilight information, Moon phases and Eclipses. It will even print conventional Nautical Almanac pages for the full range of dates; 9999BC to 9999AD. The AltAz screen can be used to plan sights or to list bodies around a point on the celestial sphere either by altitude/ azimuth or by Declination and Hour Angle.
The outlines of the constellations is the best available including ones like Sextans which rarely look like a sextant. Bayer/ Flamsteed designations are provided for over 3,400 stars together with the names of over 500 stars. Henry Draper, Hipparchos Tycho and GCVS designations are also available.
The Voyage Plan is a sophisticated tool on its own. Tracks can be calculated from positions or tracks can be used to generate positions. ETAs can be calculated from speeds or speeds calculated from ETAs.
