Assuming you're in the northern hemisphere and can escape the worst of the light pollution, you should be able to capture a pretty fair percentage of the Messier objects in pictures, even if the lens is a little dim to see them in the viewfinder. You should be able to rely on guide stars to get their rough location, though, and half the fun will be bracketing for location once you get them in-frame.

Keep in mind that these objects were discovered and catalogued using 18th-century telescopes, which really can't hold a candle to modern optics (even "eeew, plastic" consumer-grade lenses), and that your camera can see in the dark better than you can. Since Messier hunting is sort of the next step up in the entry-level hobby astronomer progression after the Galillean planets, you'll likely find a lot of information to help you in the hunt available online. And it does require some hunting for the amateur astronomer; most of them can't be observed in a hobbyist-class Dobsonian telescope unless you look at them outside of your centre of vision, and auto-finders are not usually part of a Dobsonian setup.
