Listening to the Sky [B_025555-714]

    Newer Older

    8 hours compressed into one image. To see a timelapse composed of these images try this.

    This effort spanned over 8 hours (not including a total of 12 hours of driving!), 160 exposures, each at 13 mm, ISO 250, 177 seconds, f/4. The moon rose during the exposure. The radio telescope was moving quite a lot during the night as the timelapse animation shows. I picked a single frame for the foreground.

    Or see this larger on black (in the lightbox).

    Here is the place in daylight.

    This is (almost) the summit of Mauna Kea, Hawaii, USA. Lovely place, by the way!

    Equipment: Slik travel tripod, Canon 40D, 10-22 mm f/3.5-4.5 EFS, Intervalometer, custom battery.

    If you've always wanted to take a shot like this, I have some good news for you. No, I won't fly you to Hawaii but I get so many requests to learn how to do this that together with Harold Davis, we launched Star Circle Academy.

      Gorgeous star trail Steven!
      You went south? Looks like a southern hemisphere shot
      THe gentle lighting on the foreground is so pristine. It's lit, but lightly.
      only have one tiny nitpick, and just a critique to try to perfect this- maybe a clockwise rotation about 2 degrees so that the road leading inward is parallel with the imaginary true horizon? I think that would give it an abstract balance. Other than that- wow I love this!

      Excellent capture. Now i can clearly see the difference between my stuff where the camera moved as u pointed out causing the gaps between trails and perfect arcs of yours.

      Nice trails.

      Ben: This is from the northern hemisphere, but yes, farther south. It's an advantage to be this far south since Polaris is only 19 degrees above the horizon... don't have to work as hard to get a circular arc near the earth. As for the rotation... great idea. I have done very little to this shot other than stack it and do a little noise clean up. Unfortunately it's not all that sharp and its about a six hour round trip drive to set up the shot... (Driven it 3 times so far!).

      Shubikha you did a fine job with your star trail... you should be proud.

      Great work. Really surreal looking with the smooth sky.
