   On pages 100-102 of the December 1996 issue of SKY & TELESCOPE magazine 
is an article about Georgia amateur astronomer Tim Puckett, who recently
purchased three government-surplus Baker-Nunn cameras.  They were formerly
used by the Smithsonian Astrophysical Observatory to track artificial
satellites from the late 1950's to mid 1970's, but Puckett intends to use
the f/1 Schmidt optics to search for comets.  
   There were originally a dozen Baker-Nunn cameras with 20-inch aperatures,
which together with their triaxial mounts weighed a good 
three and a half tons apiece.  Wonder what happened to the rest of these
cameras?
