When doing star alignment with my Celestron GT the slew rate either shifts or ceases functioning entirely (both in RA and DEC). I can see the object in the finder but with increasing frequency I'm having difficulty bringing it into the cross-hairs I don't think this is a balance issue because I take care of that beforehand. The mount was re-greased a few years ago so I don't think this is the problem, either. Thanks for any advice.
