As a result of the recent marketing of small pocket computers I have found much interest among navigators who would like to use them for working out celestial sights. One computer calculator (the Hewlett-Packard HP-35) in particular appears to be of considerable interest due to its ability to compute trigonometric functions with algebraic logic as well as to store and recall derived intermediate values. Not having been able to find any published work on the use of this type of equipment for the rapid and precise working of sights I have given some thought to the matter and as a result believe the following notes may well be of interest to others.
