Listening to the Sky II

This is a straightened, cropped version of an earlier shot.

 

The moon rose about an hour and a half after astronomical twilight and kept the sky a bright blue. The tiny bit of white on the back cinder cone (summit of Mauna Kea) is one of the observatories on the mountain (Gemini Observatory). The foreground radio telescope is one of the ten scopes that form the Very Long Base Array.

 

Please see this image for processing details. For even more details about how this was created, please see my blog.

 

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.

 

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