Thanks for the replies. The thing is that it has only just started to happen. I have been running off a powered hub for a long time with great guiding and image capture.
The only thing I have added is a SX USB 7 position filter wheel. This works very well and is a great bit of kit. I have tried two hubs and, different combinations of plugging them in and no joy.
I have gone back to my original setup that worked and will test the camera shortly. I have also stripped the mount and am going to do a lube and adjust and see where that gets me. I found not obvious faults during disassmbley.
Robin, I do not recall this setting. Where is it and what is its function?
Cheers!
