No noticeable vibrations unless you look for them. When you move the dob mount, it settles very quickly (in much less than a second). The spider is the only bit of the scope that exhibits significant sustained vibrations. But I only found that out by plucking the vanes. I suppose in strongish winds that might be a problem... (But it can never be as bad as a cheap EQ mount.)

Edit: sorry I thought you were still shopping around for a scope; i meant that when I handle the dob it behaves like i said above.
