    Has everyone got their solar filters and long lenses ready for the partial
    solar eclipse this Thursday?

    It'd be a shame to miss it. (Damn clouds)

    Here's a page with some good stuff on it:,448,0,0,1,0

    (not mine)

    Me - I can't wait! I love eclipses.

  2. What is a "solar filter"?

    They vary, but the most common is a sheet of aluminised mylar film which
    appears to be almost opaque (mirror-like) but actually lets through a very
    small percentage of visible light (0.001%, I think) and no UV at all.

    They are placed in front of the objective element (front lens) of your
    telephoto lens to enable safe viewing (and photography) of the sun.

    The page I linked to has more.

    Your choice.
    Me? I value my eyesight.

    Actually a number 13 welding filter is fine. Check the specs.
    Not much use on the camera though, that is where you need a solar filter.

    ....and I use a type-approved LCD "instant"-darkening welding helmet when I
    But I use a solar filter when I look at the sun.

    Call me conservative.

    (And yes, a welding filter is crap for photography. And I'm only going to
    be looking through the viewfinder.)

    Au contraire!
    Except that its going to clouded out *for sure*, I've got two
    filter-equipped cameras mounted and raring to go.

    Partials are fun....

    But surely if the full moon is at UTC 03:30 21/2/2008 it won't be visible in
    Australia as we'll be facing the sun at that time of day. The eclipse
    happens when the moon is full, not when the moon is visible, although the
    two may coincide as they did last August in the Pacific region.

  14. Nah.. Once you've tasted the hard stuff of totality (twice - Mt
    Gambier in 76, Ceduna in 02), there's no going back to them lame-ass
    partials...! (O: Sadly I think it's only about 6% here, barely worth
    a skyward glance... (o; and the weather forecast does not exactly
    look promising.

    I'm patient. 2012, here I come.

    In the meantime, there are some good chances for meteor shower obs
    coming up, see:
    Lots of technical stuff, scroll way down to the very useful table of
    observation data...

    And for those new to this stuff, there are always satellites, Iridium
    'flares', the space station, etc..
    (Log on and enter your location details - it will tell you where and
    when to look for all sorts of stuff - very cool! One night using the
    info from here I was able to watch the ISS go overhead, followed by a
    slowly closing space shuttle - just two moving points of light, but
    when you think about what you are actually watching.....)

    Don't ask me for tips on photographing this sort of stuff - I leave
    most of the astro stuff to experts. Although I did do a total solar
    eclipse site for the Ceduna eclipse in 2002:
    (Note - this page has not been updated since 2002 and my email link
    there is invalid, as may be some other links - but my email address
    here is working.)

    It will be a partial eclipse in Sydney, from about 3pm til about 4:30pm.

    (You *have* to be facing the sun to see a solar eclipse!)
    The happens when the moon is *new*, not "full".

  16. Umm, Jeff, in that post I was talking about the *lunar* eclipse on Feb
    21 (ie after midnight on the night of the 20th, for those Northerners
    who are easily confused..). As far as I'm aware that one isn't
    visible to us, happy to be corrected...

    See below for a post regarding the solar eclipse, and then you can

    Two for me too. (Same two, but different locations)

    South Coast NSW (Myrtle Mt, to be precise) in Oct '76, and Woomera in '02.
    My shots of the '02:

    My hopes for this Thursday:
    Sure, its only a partial, but I still get a buzz seeing a chunk taken out of
    the sun.

    Even this relatively lame one from '03 was fun, and worth it!

    Me too. I'll be there with bells on.
    Hell, I've even invited Doug to join me, since its in his backyard.
    (He didn't seem too keen. The invite is still open...)

    My apologies.
    I'm in solar eclipse mode right now, in preparation for Thursday, so I
    skipped right over the "lunar" bit. :-(

    BTW, my shots of the rather pretty lunar eclipse last year:

    Sorry N, I read "solar" not "lunar".

  20. I like your stuff very much, Jeff. I have to confess that in 1976 I
    didn't really have a clue how to photograph it - managed to get a few
    'interesting' shots through the cloud cover as a memento, but they
    aren't really worthy of scanning. And then in 02 I broke my bloody
    ankle just before the event and had to watch it in a rather prone
    position.. Decided not to bother trying to set up my gear, and just
    laid back and enjoyed it.

    There is just something primeval and wonderful about a total eclipse.

    Going off topic.. It's similar to the ecstatic feeling you get when
    communing with large friendly wildlife... I had the luck to be joined
    by a pod of about 25 wild dolphins on one very memorable afternoon
    while snorkeling at a deserted beach near Port Lincoln (- it was
    actually the beach used in the film Gallipoli - it's a beautiful
    location). That was absolutely the most remarkable experience I have
    *ever* had - they adopted me for about an hour. The adults clearly
    checked me out for a while before then allowing a couple of the
    younger brood to come over and join in the fun ("hey - check out this
    loser trying to keep up with our tricks.. don't worry, they are mostly
    harmless...!") I felt completely euphoric and blessed that day.

    Oh well, back to normality.. (O;
