Web6 Apr 2012 · To work out the approximate maximum altitude of a star is done as follows: 90 – LAT. So for an observer at the latitude of London (51.5 N), the maximum elevation will be 90 – 51.5 = 38.5 over the southern horizon. Then add (for north declination) or subtract (for south declination) the tabulated declination of the object you want to view.
