        {
            Angle HA  = Math.Atan2(Math.Sin(AzAlt.Az + Math.PI), Math.Cos(AzAlt.Az + Math.PI) * Math.Sin(Location.Lat) + Math.Tan(AzAlt.Alt) * Math.Cos(Location.Lat));
            Angle DEC = Math.Asin(Math.Sin(Location.Lat) * Math.Sin(AzAlt.Alt) - Math.Cos(Location.Lat) * Math.Cos(AzAlt.Alt) * Math.Cos(AzAlt.Az + Math.PI));
