It looks like your telescope's collimation is off. For a fast telescope like this, that's critical. The stars are showing spikes.
In the shot with M81 & M82, for example, that's not the case.

I observed a similar pattern when my guiding failed, it looks very much like that.

It doesn't look like it—the stars are different in different parts of the frame.
