Just to satisfy myself, I pinched the gnomonic from Wikipedia* and relabelled it from 050W, so ignore the background. Then I plotted the position of Alpheratz, Aldebaran, Sirius, and the observatory before trying the acetate. It gave the position of the owl as 22S 058W, so correct continent, but not much better than that. You'd think after all this I'd spell Aldebaran correctly every time. DaveP
