What is this artifact in my images?

Hi, has anyone got any ideas what the artifact in my images is. This time it has appeared in the top right corner pointing of the witches head nebula, if I point in the other direction it is in the top left, so is in the same spot, I think. The thing is, it is not in all of my images and seems to only occur on long exposure when the scope is pointing high. Apart from dismantling my imaging train, I have checked for stray light, looked down the tube, etc.

PS: I think PixInsight might flip the image, might be in the other orientation??
