    Re: Time from 2102-D starfinder

    Because I considered this response to be inaccurate, it was able to trigger 
    the thought process to make it work for me.
    
    The problem with the response was that you never use GHA directly with the starfinder.
    
    To draw sun, planets, moon onto the disk, you use right ascention.
    
    To position blue disk properly, you use LHA of aries.
    
    So now I'm thinking that if you get meridian passage of aries from the daily 
    pages of almanac and correct for your longitude using arc to time, it gives 
    you the exact time aries passes your position.
    
    From this, I can mark off each hour as 15 degrees on the rim.
    
    Does this do it?

    With the appropriate blue template in place, turn the disk on the starfinder
    until the azimuths and altitudes of the bodies on the face of the starfinder
    match what you see in the sky.  Read the GHA of Aries from the pointer.  Open up
    your Nautical Almanac to the appropriate page and find the time at which the GHA
    of Aries matches that shown by the starfinder.  You will probably need to go to
    the Increments and Corrections pages too. The result will be approximate.
