Listening to the Sky [B_025555-714]

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.
