Last Sunday evening, the thin crescent moon was prominent in the sky. It was also accompanied by a bright object not too far from it – Jupiter, the fifth planet from the Sun and the largest planet in the Solar System.
When I set up this shot, I know I want to capture the earthshine. Earthshine is the night side of the moon, i.e. not in direct sunlight, illuminated by the reflection of light from the Earth and can be seen shortly before or after the new moon. I also want Jupiter and other stars to be sharp and not as star trails, which means shutter speed of only a few seconds at most at 200mm focal length. In order to accomplish this, I need a long enough shutter speed to expose the earthshine but short enough to keep Jupiter and stars as pinpoints. The final setting is 1 second of exposure @ f/4.0 ISO 500.
Juniper is the bright spot on the left in the image above. Also clearly visible are the three Jovian’s moons – Callisto, Ganymede and Europa. Io is barely visible in the high-res image. The streak towards the middle of the image is a satellite fly-by.
