I use an ES127ED on the CG-5 and have had three rather minor issues: At times the diagonal hits the tripod legs when the scope points too close to the zenith, and this sometimes happens unfortunately during moving to find the set-up stars. A friend with the same rig solved the problem with a pier extender from Orion, but that adds more weight (and cost).
Quote:The mount often stops during a slew…. waits up to 10 seconds, and then continues on to its final position. It sometimes does this *twice* before getting to the right spot. It never does this with less weight.
Quote:There is a little more shake during focus than I’d like, even with vibration pads under it.

Quote:Just so you know, the AVX has a 144 tooth gear so the worm period is 598.362 seconds.PECTool handles this with no problem, PEMPro may need a bit of juggling to set the right period. I've let Ray know so.Chris
Quote:The image is nice. The main question I have is whether or not the declination axis on the vx has less (or no) stiction/backlash trouble relative to the cg5. Those of you with the mount, can you comment on that?

Quote:Well, I don't really care if it has bearings, no bearings or little magical leprechauns inside it. I just want to know if it moves better in Dec than the CG5. I am surprised you aren't getting faster feedback from them.

Quote:A polar scope is easier and faster. And, in my hands, as accurate. Neither preclude a drift alignment. Is it supposed to?
