My brother-in-law is a pretty good photographer (as you may remember). He just posted this lovely picture of the waxing gibbous Moon tucked in amongst the clouds at sunset:
Click it to embiggen. It's not hard to get nice shots of the Moon, even during the day, though to get one this nice it does take a bit of experience and work. But it's not all that technically challenging, and since it's IYA 2009 anyway, I encourage everyone to give it a try. The Moon is bright and easy to spot, making it the obvious target for a beginning attempt at astrophotography. But you'll need a telephoto; the Moon is smaller in photographs than you might expect. Experiment! Play around! And if you get nice results, link to 'em in the comments. Let's see what you've got.
