    Another Wow ! regarding 2102 is that it is a year of a full Moon Xmas as was the Xmas that Gilbert Rude invented the star finder (1920). Coincidence ?

    I would say that I don't believe in coincidences, but WOW!

    On an unrelated subject, on the left-hand page of the attachment there is a picture of a Felsenthal Coordinate Transformer.  I actually have one of them.  When taking the Power Squadrons old Navigation course, we were taught how to transform coordinates using the "meridian diagram" (projection on the plane of the celestial meridian).  I thought that the meridian diagram was a great tool for explaining certain phenomena, but it was eliminated from the course in the 2009 edition for being of no practical use.  But now some of us are trying to get it put back for the 2015 edition, at least to the point where it can be used for explaining things, if not for transforming coordinates.  In any case, there is a coordinate transformer program for Windows, Navtra, on the Power Squadrons web site, http://www.usps.org/national/eddept/n/tools.htm.  A few months ago got it to work on 64-bit Windows, but I had to sacrifice use on Windows 95 and 98 to do it  :-0
