    SkyPlot is a DOS program.  It has old style menues. You enter values on a 
    setup screen, then go to a separate plot screen, then run a step that builds 
    a "PRN" file, then display/print this file with wordpad or some such.
    I really like it.  The print file lists the HC and Zn of all 57 nav stars plus 
    sun, moon, and 4 planets (if visible).  It has a disclaimer that the planet, 
    moon data may be off by more than a mile.  So what!
    It will also display/print an image that shows you what stars, etc you would 
    see for the date, time, DR, you entered.
    A really agravating, nit picky little thing that bothers me every time I use 
    it is that you enter lat/lon in degrees and decimals even though it gives you 
    back degrees and minutes.
    I've tested it fairly thoroughly because I use it to set up plots for a celest 
    nav class.  Our plotting has yet to discover any serious error on the part of 
    the program.  (By serious, I mean a discrepency large enough that it wasn't 
    accounted for by our inability to draw straight lines, measure distances, or 
    do simple arithmetic)

    Subject: [NAV-L] Star Finder Software
    I'm wondering if anyone knows of a good freeware option for predicting star,
    planet, moon and sun altitudes and azimuths in the 2102D style. I know Celestair
    sells software called SkyPlot for PC and I'd be interested to hear reviews even
    though it's not free. I recently found an online program at
    www.weatherunderground, the link is:http://www.wunderground.com/sky/index.asp.
    It's a very nice program but the input for location is zip code rather than
    lat-long so it's not much use for passage planning and the plots don't print out
    very well.
