    Default Happy Autumnal Equinox!



    Nights will soon be shorter than days for northern hemisphere
    observers. Longer nights translate into more (dark sky) observing
    time.

    Happy Autumnal Equinox to all and to all a happy new observing season!

    You mean there will be more darkness than daylight in the Northern

    natural length of the day via noon and the 24 hour day.Those who say
    the "days are getting shorter" hardly are aware how imprecision causes
    so much trouble yet considering you will probably believe the Earth
    rotates through 360 degrees and combines with the orbital motion of
    the Earth to create the observed 24 hour noon cycle -

    http://en.wikipedia.org/wiki/Sidereal_time

    I will not complain that when offered a new way to look at the Equinox
    using modern time lapse footage of our planet from space to show how
    the slow orbital turning of the Earth to the central Sun brings the
    rotational poles in line with the circle of illumination thereby
    generating equalities of daylight/darkness ,the offer is refused or
    ignored.

    You clearly want your celestial sphere observing and nothing else but
    then the price is that you are an astrologer with magnification
    equipment and not an astronomer.



    For me,it means that there is a global asymmetry between the orbital
    motion of the Earth from the last Equinox to the next Equinox in 6
    months time,this is how a structural astronomer thinks as opposed to
    those engaged in the magnification exercise who neither know nor care
    for a once noble astronomical heritage.
