F1 - - Index of Selected Stars - (West to East) - - 10/03/2004

The Nautical Almanac gives the location data for 173 stars, but from this listing 57 stars have been chosen from amongst these on account of brightness and distribution in the sky; they will suffice for the majority of observations. The location of a star is given by its sidereal hour angle (S.H.A.) and its declination (Dec.). The locations given below are rounded off to the degree of angle and are an aid in finding the star on a star chart, but for sight reduction, more precise values will be needed from the Nautical Almanac.
