Hi Pete,
We've got the same scope /camera, so I saw this the year before. But in my case, the defraction unfortunately cut right through the head of the horse - what a bugger to see after a full night of imaging. Even with dithering, it was still noticeable. Just have to figure out the best camera angle combined with the right guide star.
Cheers
Steve
