Have just hit the list archives:

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.
