I bought an Esprit 80 recently and the R&P focuser slips easily.
The focuser looks fairly well designed but is way out of adjustment and worse, they've thread locked everything making it difficult to adjust.
There are two Teflon slides with two screws each that I tightened ~1/16 to 1/8th turn to remove the wobble from the drawtube and provide a little friction. Originally the drawtube rolled in an out just tilting the scope when I had the pinion removed. I didn't pull the drawtube all the way out as I recall reading somewhere that parts are held in place by the drawtube.
I want to get the micro-focuser off so I can put more tension on the bearing to increase load carrying ability, but the grub screw is so tight I've rounded out the hex head, so now I've ordered a screw extractor set to get that out. Once the micro-focuser bearing is tightened the focuser should perform very well.
The optics look fairly good, just a slight dent in a star halo.
