I see you live in PA. You will have only seconds for a partial not total eclipse. The shadow is moving at 1,678 mph. Best results for totality will be speed bracketing starting at 1 second moving to 1/1000th using a fixed aperture...you see, it really is rocket science.
It depends on where in Pennsylvania you are... Observers in Erie, PA will see totality.
Also, YOU are moving at close to the same speed as the shadow. Relative to an observer the shadow is moving much slower, and an eclipse may be shot at a MUCH slower speed than 1/1000 sec. Think of looking at the Sun. Does it appear to be moving across the sky at 1,678 MPH? With the right filter, you could take a picture of it at 1/30 sec. or less.
