CGE Polar Alignment Kit

I'm trying to find a Finderscope, Polar Axis Kit for the CGE mounts, it was Celestron Part No. 94222, does anyone have one for sale or can anyone give me some info on how they work and why Celestron discontinued them. I have a lot of experience with this mount, but for astro-imaging I would like to establish a little more accuracy with a more precise alignment.

Thanks,
Brian

For the best polar alignment you will want to learn how the drift alignment method works. Polar scopes can get you fairly close but with a little practice drift alignment can be done fairly quickly, and the accuracy will be superb. You will also want to be familiar with cone error, which in most cases can be ignored, unless it introduces a fairly large error. The following link describes the various alignment schemes fairly well.
