1 Pub 229 Method

Celestial sight reduction by equations is a quick and inexpensive option for solving running fixes, azimuth for compass error, and ... Use Triple Interpolation of Declination, Latitude and LHA to determine Zn (True Bearing) to a Celestial Body (in this case Spica). In this video I will go through calculating the Azimuth (Zn) and Height Calculated (Hc) using HO229 to reduce the star Deneb.
