I get teflon tape that's used for plumbing (for creating a seal when joining pipes) wrapped a few times around the plastic bearings (i.e., the plastic rests on the sides of the base that Allan's pic points out with the red lines). The teflon tape still tends to stick to itself so no need for adhesives. It's quick and easy and works well. The teflon tape will wear through over time (slowly), but you can easily add a few more wraps at any time.
There is more that can be done with the friction against the sides of the base (ebony star and teflon pads) but that's more tricky and takes more effort, required bits are harder to get. (Though it'd probably be worth doing.)
I tried many different kinds of lubricants, including dry ones (e.g., DryGlide, graphite), but have never been happy with the results.
raymo is correct that balancing the scope is very important. You should need only very light tension on the alt bearings. (It's actually compression but everyone calls it tension.)
