Sigh... after fiddling with the sights and trying to find what altitude for a given time and AP gives a plausible distance to the GP, it seems there is about a 1.3 degree error between my recorded altitude and a more reasonable altitude. The problem is my altitudes are all too high. If, as has been proposed, I was using the top of a distant mist bank or cloud bank as the horizon, I should have altitudes that are too low because I'd have measured from Betelgeuse to the top of the clouds instead of further down to the true horizon. Instead it looks as though I used some point *below* the horizon as the "horizon" for my shots. I'm hard pressed to explain that much error. Rick S/V One With The Wind, Baba 35
