Matt do you get this also with long focal length eyepieces in your scope?
I do and its a symptom of a large exit pupil and astigmatic eyes. I get little flares/spikes on star images noticeable with exit pupil sizes > 2mm.
If your scope is an sct, you likely never see an exit pupil big enough to notice it.
