Erick,

I did some research into "Ebony Star" and user comments and results seem to praise this concept very much. In fact it is mentioned that this is what is used on Obession telescopes?

My understanding is that it some side of material that you stick to the top base of the az base. Then this material glides really well with the teflon pads that are on the bottom base..

Could you be kind enough to explain why this works so well? And also If i am understanding the concept correctley?
