Mike Nice work. You've gone from an average error of -0.45' to 0.02' and a standard deviation of 0.48' to 0.25'. How about some star lunars at 90d separation.I too would like to know what you may have changed, especially if you used shades and did the observations on the fly, or employed "set and wait."
