Asi 6200mm issue

I appear to get some sort of weird artefact in all my images. Is this ampglow, reflection or what ? I get it on different targets.

That looks like an off-axis reflection. Is there a bright star just off the field of view? Was the moon somewhat nearby for these images? Does this reflection happen no matter where in the sky you are pointed, or just for this image of M101?

Yes you are correct thanks :-) it does look like an off axis reflection. Now trying to work out where it came from.

There is a relatively bright star but it’s quite far from the edge of sensor. Also my images of M106 have the same reflection.

So my thinking it must be a light or something local to me ?? Can’t think what to be fair
