Although you don't want to be too far off as drift in the eyepiece will be an issue. You want it good enough to stay centred in the frame for a short while, ideally the eclipse duration. It depends on how long a focal length you are using. 24mm is no worries, 1000mm is.
I found during the Venus transit the main issue I had with my scope on a regular untracked tripod was getting framing right. Its awkward when you are using a scope and the object is moving off the frame continually.
You could easily end up with a series of poorly framed images or blurred images because you were nudging the camera to get it into position or lose an opportunity because of that.
