    Re: FW: The N )VA Crescent from a different angle

    The thread dates from Jan 2009. The almost final result from Frank:

    Hewitt, you wrote:
    "It seems to me the thing about watching the sun from the North Pole is its
    altitude is the same as its declination. That is, on the say of the summer
    solstice the sun's altitude would be 23.45°. It would circle the horizon at
    that altitude, gradually declining day by day till the equinox when its
    altitude would be 0°. That would be sunset. (Obviously, I'm ignoring

    Yes, and so the Moon could never be seen there in that orientation either.
    It's intriguing to me that people happily forwarded this to one another
    without ever considering WHY they think it shows the North Pole. I suppose
    most people are under the impression that the view from exactly at the pole
    must be unique, eery, or at least unusual. BTW, where's the workshop? Behind
    the photographer?

    "The moon being so large and the reflection in the water (ice?) indicate it's
    a composite, but it is beautiful."

    Not even a composite. It's a pure digital fantasy. But here's an interesting
    challenge: the next time the crescent moon is very close to a bright planet,
    I propose attempting a real photo that duplicates as nearly as possible the
    appearance of this digital image. Then we start a new email forwarding game
    and see how many people happily assure us that, "as everybody knows," it's
    not a real photo. For starters, what's the range of latitude where the horns
    of the crescent moon can be exactly horizontal?
