If you've been watching the skies lately, you've noticed that the Moon has been swinging closer and closer to a mysterious planet low in the sky. Now thanks to heavens-above.com the planet is no longer a mystery! It's Jupiter! 木星!

Year: 2008  Month: 7  Day: 17  Hour: 22  Minute: 36

As you can see, the Moon and Jupiter are right next to each other tonight. Taking this prime opportunity, I whipped out my camera, set up the tripod on a stool on a chair on the balcony, and took some photos on various zoom levels at various aperture and exposure settings. Here's a photo illustrating the distance between the two objects, overexposed to get Jupiter two show up (it's very clear to the naked eye, though):

Obviously the moon is way, way overexposed, so I closed the aperture a bit and shortened the exposure time.

Back to a longer exposure time, I zoom in on Jupiter. Originally I had thought it might be Mars, but who could mistake the deep sky-blue color for Mars' red surface???

Lengthening the exposure time even further to probe for details, I captured all four of Jupiter's Galilean moons: Ganymede, Callisto, Europa, and Io! Nice!

That's all for tonight. It's a pretty good capture considering the warm Shanghai atmosphere, the Zhangjiang High-Tech light pollution, and my shaky little tripod.

Your camera is better than mine, you could probably do just as well or better. And isn't it nighttime over there right now? Same sky...
