    At video minute 7:08 you will see the addition mistake which results in an incorrect local hour angle and thus ruining the sight reduction before it is started :( Arithmetic #{at}!%&

    Here is a YouTube haversine sight reduction using Nories.

    https://www.youtube.com/watch?v=Dv2XixTDlrU

    The instructor made a few mistakes. DR Latitude is 19* 42' N (not E). Not sure what was going on with the 35 NM intercept ( I think it was just for a plot demonstration ). The intercept should have been 1.7' toward on an azimuth of 220.2

    As you can see it took over 20 minutes to walk through a single sight reduction.


    Chichester must have been cursing all the way to Sydney ;-)
    ------the sight reduction before it is started :(
