    Skywatch

    Looking at the sky. Always. Day and Night.

    Hi Robert, with the sharp shadows on the dish, it looks like you are in bright sunshine. Why so dark?

    I'm guessing it is moonlit, EXIF sorta confirms it;

    Canon 40D, shot at 20:51 on 10th September; 180 seconds at f/8, 200 iso at 17mm

    Great shot Robert.

    Cheers,

    Cool shot, though I do wish it were a bit brighter.

    180 seconds for those streaks of clouds? That doesn't make sense to me.

    I hadn't thought of that! I have been to Wales, and the one thing I remember most is the really strong winds!

    Re: Skywatch

    Sorry for the late reply. It was indeed a litte stormy that night. Lightning did strike in the far distance that caused the yellow looking clouds on the right side of the picture. The small high clouds over me moved very fast in one direction. That gave the sky that stripe look. I removed all startrails between them.

    Very interesting shot Robert..I love the clouds, and even better that you
    caught some of the light from a lightning flash during the exposure. Was the
    dish pointed at the Moon during the time you took the image?

    No. In that case the shadow of the subreflector would exactly hit the horn antenna in the middle. I hope to get a picture one day when the dish is pointed at the moon.

    Re: Skywatch

    I missed this and only saw the thread today.

    That is a very nice image, Robert. The artistry and skill of the photographer is in seeing the opportunity presented by the fact that, from that viewpoint you had the cloud blowing directly from back-to-front overhead, and getting yourself into the right position to capture the photograph. If the cloud had been going from left-to-right, the image would not have worked.

    So, I think it is a very, very good composition.

    A great shot !
    Very dramatic with the strong lines of the dish against those angled streaks of cloud.

    And I don't think it wants to be any lighter, the muted tones give it a wonderful twilight atmosphere, its one of the things that makes it different from the run of the mill.

    Re: Skywatch

    I was a little bit lucky that night. This picture has so many components on that I did not have any impact, e.g. weather, wind, full-moon, positioning of the dish, etc. For viewing it on a screen, it's light levels are just fine I think. I also made a print of it. For that I gave the picture a little bit more brightness.

    I think the first (portrait) is a much stronger image than the second (landscape). Having the dish pointing upwards into the vast expanse of the sky makes this a very powerful composition, in my opinion. The low angle of the light also contributes to significantly to a very good image.

    Re: Skywatch

    Robert, I agree with Donald.
    I also wonder if this image could be better at a different time of day?
    Lower contrast/different shadows?
    Thanks for posting more photos.
