If your scope tube is metal like mine it'll throw off a digital compass. I bought a cheap one for $20 to play with but quickly realised it won't work out. (That's okay I can use it with my Garmin GPS, which doesn't have a compass, though it still can display direction if moving)
Much more accurate to set azimuth based on a star.
I also bought an inclinometer. I think that will work out, but haven't used it much. This is the one I have.
