    Anyone got any tips for shooting this tonight with a tripod,
    70-200 f/2.8, 1.4x and 2x extenders? I read stop down to f/11 or
    so. Anything else to look out for?

    Expose for sun lit. Moony 8 rule. Manual WB to daylight.

    Thanks. LOL I read on a forum somewhere a guy asking what
    flash settings to use.

    I thought maybe that Moony 8 rule may not work. We are not
    dealing with a fully lit moon here. During the eclipse it's red
    because of light from the red end of the spectrum bending around
    the earth while moon is diametrically opposite sun. Surely that
    light will be not as strong as normal full moon?

    Of course, try some average settings and have a look and adjust as needed
    really. Don't drop your shutter speed too low. Plenty of time to experiment.

    You can do it at a much more civilized 7:00-9:00pm in Australia, mate.

    Question? If you stop down to f11 why would you need
    an f2.8 lens to do it with?

    Think teleconverters......

    I need to use a f/2.8 lens because it's the only one I own ;-)
    The above is my gear list in part.

    Plus, as someone else just mentioned, when using a 1.4x TC you
    lose one stop so it becomes max f/4 lens effectively.

    When using my 2x TC it's 2 stops, so it becomes a f/5.6 lens.

    Plus I understand using lenses at 1 or 2 stops down from their
    max aperture gives sharper images - sweet spots etc. I haven't
    personally tested this, but others have.

    Fair enough "Troy". If you have a good quality 70-200f2.8 lens you
    should get good sharp images at f2.8 Since you will only be shooting
    at points of light you might gain by sticking with f2.8 and take
    advantage of the faster shutter speed. The 1.4x or 2x converters may
    not gain anything if you loose resolution while doing it.

    Well, I set the alarm for 3:30 AM (peak totality) without preparing and
    discovered that even wide open with a 300mm f/2.8 plus teleconverters
    that I needed to crank up the ISO to avoid star trail issues. It all
    took longer than I thought to figure out, anyways here's what I ended up
    with: http://edgehill.net/Misc/misc-photos/8-27-07-eclipse/pg1pc1

    Not so fast, "Frank Arthur". Since when is the moon considered to
    be a point of light? The moon is also fairly bright, so you
    wouldn't want to use a wide aperture. Maybe f/2.8 if you're more
    interested in capturing the penumbra. The TCs will also help if
    they're decent quality.

  13. Additionally, when recording punctual light sources (e.g. stars)
    the amount of light captured and focussed on one pixel is directly
    determined by the size of the (effective) front lens.
    And if you stack them, it becomes a 196-560mm f/8 lens.

    In my limited experience, if you stack teleconverters, you get
    a much better quality if you stack them
    Lens -- 2x -- 1.4x -- camera
    than
    Lens -- 1.4x -- 2x -- camera
    At least my 70-200mm f/2.8 IS on a 20D does work best one stop
    down, not two, with teleconverters, when it comes to center
    sharpness, with wide open becoming better than 2 stops down
    at 2x and above, and little difference between wide open (f/8)
    and one stop down (f/11) with stacked teleconverters.

    Without teleconverters f/5.6-f/8 on the 20D is best for center
    sharpness.

    Whoops! I pushed the send button before writing.

    No the moon is not a point of light but those stars surrounding them
    are and if you can get them to appear as seen it is a big advantage.
    I haven't tried this moon shot but apparently f2.8 is not too bright
    for it. Paul Furman who did the series and showed it to us to enjoy
    did not think f2.8 was too bright an aperture especially since he used
    teleconverters and had to crank up the ISO. Even without the
    converters
    at f2.8 there would be fast enough shutter speed without overexposure.

  16. Those are great pictures. I also did some looking at the rest of your web.
    must be a great way to earn a living. even if a lot of money is not made.
    to spend your life taking pictures :).

  17. Unfortunately, taking pictures is the smallest part of the
    job, or so I am told by professionals ...

    Once the moon is eclipsed it is very dull, not bright at all.
