> Did you clear the distance for refraction? Yes. In an elegant manner. Alex and I usually agree on the observed angular distance unless one of us has made a blunder. The "what have I missed" question is more directed to the two (?) stars in the same general area. Near 0d S declination. Perhaps 2d SHA difference. One (Mintaka) shows up in Omar's Hipparcos Catalogue but not in the almanac (the best I can tell). The other, delta Orion, shows up in the almanac but not in Omar's catalogue. I dimly recall some posts on star lists and names a while back, but I'm dealing in specifics here. Apparently two stars very close to each other, but only one shows up at a time depending on whose radar scope you look at. Hence my gut feeling it is a blunder on my part, but I cannot locate the blunder. Thanks Bill
