    Re: Star - Star Observations

    Curses for brain/typo errors.
    Last posting by me:-

    "Agreed: from calculated true altitude to a calculated apparent refraction, refraction is to be added, as in the zenith diagram in fact".

    Should read:

    Agreed: from calculated true altitude to a calculated apparent ALTITUDE, refraction is to be added, as in the zenith diagram in fact.

    P.S.
    On other internet discussion groups/fora it is possible to correct text afterwards for a time; is it not possible to implement this here?

    Douglas Denny.
