Wouldn't the image be perfectly circular and not have any chunks out of the side of it? And not a small circle in the middle with a mostly formed outside around it? Bokeh would look like this o or a completely filled in circle. I still say the opinion is out on this until we can see other examples of similar "artifacts" that can produce this effect, this does not look like any thing I have seen before that is known.
I believe there have been posts with links in this thread that show polygonal bokeh and explain them. Photographers exploit it for effects in photos.

concerning that, what is written about this suggests that it could be a catadioptric lens bokeh effect rather than polygonal which would produce a donut shaped blur from a point of light.
i don't think it is that either as this would be something uniformly seen due to the lens, from whatever point of light was at the right magnitude to create the effect. in other words... you have an image full of light, why are there not donuts all over it? doesn't make sense.
this is more than likely, imo, a reflection of the entire image and then duplicated once more less opaque... something to do with the telescope, yes... but since the entire image has light all over it... to think it was merely a blurring effect of the lens would suggest that we should be seeing a multitude of donuts or polygons.
we see two, one being more transparent than the other because it is a reflection of the first faulty reflection. a duplication of the first glare.
