EQ6 Tracking problem

Last night I had my first real try at capturing a DSO. An easy target was the way to go so M42 was picked. While the resulting image is OK (other than some trailing) I think I have a bit of a problem with my mount. It doesn’t appear to be tracking smoothly.

The first attached image shows what the trailing looks like in one image (I have zoomed in on one are and all images are from the same area) and then the next attached image is the very next frame. The trailing is in different directions! I stacked all the images in startrails to see how it looked over the whole run and a section is shown in the third attached image. The following image shows what I would call rabbit’s ears and then the next image shows a frame with much better tracking. The last image shows a very quick stack of all the frames. It is the result of 19 two minute exposures.

Can anyone tell me what is going on? I am using a EQ6 Pro mount.
