We’ve figured out all sorts of ways to get the faintest and the mostest out of CCD chips, DSLRs, and videocams.  But what about your eye?  Are you sure you know all the tricks?  Why your daytime glasses matter, why to hug your trees, why the universe yellows as you age—and do bilberries really work?  Come rouse your rhodopsin with Alan MacRobert, Senior Editor at Sky & Telescope.  Alan MacRobert became an amateur astronomer in 1964, stuck with it for a reason you ought to learn and tell others, started subscribing to Sky & Telescope in 1966, and joined the magazine’s editorial staff in 1982.  He has items filed away for Celestial Calendar coverage in future issues as far ahead as February 2056 (take a guess what this one is).  “I may retire before I’m 105” he says, “but it’ll be in the file drawer whoever’s sitting in my chair.”
