It shouldn't be a problem. It wasn't for me. Just make sure your square to the eyepiece and you can see the whole field of view. As long as its close to the centre your scope will track fine. If you're going to do some imaging in polar and you don't have a web cam and say, K3CCDToolsV2, you'll need one for drift aligning. But don't torture yourself. Get a web cam and K3. Its soooo much easier and quicker
