Two crucial things to know.
Visual astronomy and imaging are _completely_ different. The camera is not some advanced version of your eyes, it's completely different.
One setup will not be good for both.
The mount is the most important part of a DSO imaging setup. NOT the scope or the camera.
DSO imaging is both complicated and expensive. The bigger the telescope the more expensive it is. At your budget the only reasonable setup is camera tracker/camera/lens (a small telescope). And even that will be a stretch, unless you use an existing camera and lens. But it's an excellent way to start in DSO imaging.
Before considering imaging, or, especially, buying anything, you should read this book.
The best visual setup in your budget is a Dobsonian telescope. If you buy the right one, you could image the Moon and planets. Buy the wrong one, you'll be unable to focus with a DSLR. In any event, a Dobsonian is of no use to a beginner for DSO imaging.
