More likely to be this: the autofocus on my 350D (virtually the same camera) has problems unless you set it to use the centre point only and get that on a bright star. It won't take if it can't focus. You can also get around it by switching the lens to manual focus! Beware though that focus for the night sky isn't quite at the end of the focus range and it's very difficult to see whether it's in focus through the viewfinder, you may have to experiment.
