Thanks Dom for confirming my hunch. Next question -what can I do about it? Nicest would be if AsiAir had a setting one could change from Eq to AZ, so one could at least properly control the scope and use at least some of the nice features. Maybe I should get a wedge, though everyone seems to say that's a poor substitute for a proper equatorial mount.

Yes, after I adjust focus (actually on a 6SE) it wobbles and then dies down in a couple of seconds. My biggest problem is wobble caused by wind. Presumably this also would be less with a sturdier mount.

I also have a Celestron 6SE, the same camera and an ASIAIR pro, which provisionally I've just mounted on the tube using duct tap. At the moment I have several problems. (1) the wifi signal is weak, so I added an extender, connected by an ethernet cable (2) the wires going to the Asiair tend to get wrapped around the telescope - especially when it slews by a large amount (I find that often instead of moving 10 degrees to a target it will often slew 350 degrees in the opposite direction. (3) although I can manually slew the scope using the 4-arrow Asiair display I find it doesn't work right. Note that the 6SE has an AZ mount while the Asiair is primarily intended for equatorial mounts. I use it mainly for the wifi and camera control. I first do a 3-star (skyalign) align using the handset. This works reasonably well in providing go-TO to the desIred object and gives pretty good long-term tracking. But when I switch from the eyepiece to the camera I have to recenter the object (mainly because the FOV is smaller), and while I would prefer to do this inside my warm house using the Asiair controls (main reason I got it!) the moment I adjust the centering the object starts to drift off. The only way to stop this is to switch off the tracking on the Asiair then switch it back on again - by which time I need to recenter again! So I end up having to go outside again and recenter using the 6SE hand-controller. Very annoying. Perhaps it's because the asi-air thinks I have an equatorial mount (but that does not fit with the initial good tracking, which is definitely going through the asiair because drift starts immediately I switch off the tracking on the asiair. By the way I was born in Leeds and grew up in Wakefield!

What causes the "wobble"? Vibrations through the ground, wind, touching the scope? If you eliminate all these, could there be other sources of wobble?
