Orjan:

They say that "the devil is in the details", ad while "they" are often wrong, here they are dead on.

As to one making silly mistakes, I could regale all here with an almost unending tale of mine. The following will serve as an example. Running a reduction of the sextant data Jeremy furnished, his ship being fairly far East, and not very far North of the equator. Given the East longitude, one adds it to GHA to determine LHA I did this with the first set of sextant readings, obtaining reasonable results.

Going on to the second set of sextant data, I got LHA's that were absolutely ridiculous, and I kept getting the same results, going through the calculations several times. Finally, after some cussing, some head scratching and invocations to the gods and goddesses, I noticed that rather than adding East Long. to GHA, which one is supposed to do, I was subtracting, ergo the truly ridiculous LHA's and other results obtained. Interestingly, I cannot, in honesty, put it down to "computer error", especially when human stupidity was the culprit. Drum rolls if appropriate.
Life is a never ending learning experience, it seems.
