In the world of taking observations, as opposed to reducing them, I was thinking of the observations that are the most difficult to shoot at sea and thought that I�d make a short list. I am wondering what others might think and how they rate different observations in order of observation difficulty. I am not going to list such main stays as sun lines, azimuths, and upper transits. By difficulty I mean to not only observe them, but to get useful data. In any case, here is the list of exotic sights that I�ve taken in order of difficulty 1) High altitude sights of the moon (Ho >89 degrees) 2) High altitude sights of the sun 3) Amplitudes of stars/planets 4) Amplitudes of the moon 5) Nighttime (by moonlight) star fix 6) Lower transit of a star (due mostly to low altitude) 7) Lunar distances I�d be interested in hearing what other sights have proven troublesome to navigators out there.
