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
