Lunar eclipse photos

The Mungo Says Bah blog has some nice ones.

In case you’ve forgotten (or never really knew, as in my case), a lunar eclipse takes place when the earth gets right in the way of the sun, (i.e. right exactly between the sun and the moon) such that the earth’s shadow (lighter shadow is the penumbra, and the much darker umbral shadow appears later) appears across the face of the moon. The blood-red or orange colour is the result of the final bits of sunlight that are able to refract around the earth’s atmosphere - the earth’s atmosphere blocks the blue light and allows through predominantly the red portion of the spectrum which we see.

I hope one of my parallel-universe selves is an astronomer. I keep thinking I’d love to stare at stars and planetoids all night but never seem to get around to it.

    Thank you sir! I had fun, but boy was it cold….

    I have posted a link to your blog in my blog roll, hope that’s alright.

    All the best,

    Mungo

    Yeah, I spend about 20 minutes taking shots right at the height of the eclipse. I was bracketing this way and that just trying to get a couple decent shots. I got one.

    I have an alternate self that is an astrophysicist, so I understand the attraction to watching the celestial sky. My husband and I watched the eclipse through the partly cloudy skies.

    You should have seen it up north here Tom!
    Spectacular!

    Attend some “star parties” like those hosted by the
    San Jose Astronomical Association (www.sjaa.net/sjaa.html).
    They’re specifically aimed at the public, and you’ll find
    plenty of willing & knowledgeable amateur astronomers who
    will give you a look through their telescopes at the
    wonders of the nights sky. Start with a couple of the Friday
    night events at Hogue Park in SJ, and if that catches your
    fancy, make arrangements to attend one of the ones that
    are held at (drum roll…) Henry Coe SP! Spend a day
    exploring the Earth on foot, then hang around as darkness falls
    to explore the heavens at night.

    Oh, and if you think terrestrial photography is challenging, try
    astrophotography — especially through a telescope. I haven’t
    kept up with this, so I don’t know if they’ve made the switch
    to digital equipment. This might be one area where chemical
    emulsions are still superior.
