I assume this was done so as to indicate at what limit your instrument should reach in order to get at least some resolution into stars. I believe this was done by some compiler decades ago (Shapley, perhaps?), and is no longer continued. -------------------- Home-made 11X50 right angle bino, 8.1 deg.
