Most DSOs are too faint to record in exposures of a fraction of a second, the telescope must track them and the camera must make a lnog exposure (minutes to hours).
With the Moon and the brighter planets, you have enough light that even a simple digital snapshot camera or webcam can make an adequate exposure in a fraction of a second. Hence, since they don't move faster than about 1/4 of a degree per minute, they don't blur.
You can remount a dobsonian (it's a newtonian telescope on a dobsonian mount) on an EQ and track with it. You can also track with what's called an EQ platform or Poncet platform, but with exposures longer than about 1 minute you will get star trails in the image due to what's called field rotation.
In summary, for bright objects like the Moon and some planets, you can do short-exposure astrophotography with a typical dob. But for DSOs you need longer exposures than the mount can accommodate with blurring or trailing.
