July 26, 2008 #009 - Planisphere

All backyard astronomers have probably used a planisphere to check out the night sky. Today you can get hand held units that you can point at any of thousands of objects that will read out information. They run around $250. You can see them advertised in any astronomy magazine. Tonight I scanned to the blog my old Star Explorer. The back says the forth printing - 1944 - 45th Thousand. It was given to me to use when I was a youngster and probably sold for less than $2.50. This was high tech analog stuff.
