Todd Have just hit the list archives: http://www.i-DEADLINK-com/lists/navigation/ In January 2005 there was a discussion you might want to check out under: Sight Reduction Formula Question In it George Huxtable et al examine several formulas for finding azimuth. In the textbook formula I provided you, I do indeed run into trouble with extremes (even a hypothetical body with LHA 5, Dec 60 N, and Lat 40N produces azimuth figures that I know are off--can't be 0d. Extremes are not handled well with the formula I provided and my TI-30XA. For example calculation of the Hc and azimuth of Polaris gives me an azimuth for Polaris than cannot be right--to0 large. Not by a ton, but still... Might be worth a read. Bill
