Yes, the halo is interesting and I've seen the same thing sometimes with other refractor set-ups.
I think the halo is a reflection off the QHY8 UV/IR filter, in turn being reflected back off the telescope objective. It's only an issue in extremely high contrast situations, such as this one with the bright star in amongst diffuse objects.

I'd like to eliminate it if possible... does anyone here have any advice?
