Reflections and the QHY8

I am wondering whether other QHY8 users are encountering reflections like this in and around the Horse, Flame, Alnitak. The image is with an ED127, prime focus. No filters, flatteners, reducers or anything else in the optical path except the front filter on the QHY8. But I find it difficult to figure how that could cause the strongly directional blast from the top left. Any ideas?
