Understood. Yes, it is an artefact, but a fun and sometimes attractive one.
My CV 40/1.2 produces huge well defined large sunstars at the drop of a
hat---too much of one spice can spoil the soup. It is not the right lens for
many situations as a result. Sometimes I like the effect especially in
nightscapes or low angle sun peeping out from an obstruction. The OMZ 50-250
has straight aperture blades and has decent sunstars.
I honest to goodness don't know which of my lenses produce what sort of
sunstars.
Remember this shot?

I do, and I still like it. I'll cop out by noting that those are not "Sun"
stars.
I think I may be a 4-5/10 on the sunstar fan scale whereas Moose may be a 1.
Curiously the CV 50/f2 apo has a virtually round aperture shape at F2 AND F2.8
but polygonal with defined sunstars after that. It keeps the bokeh better at
wide apertures. A nice review of sunstar effects:

And here's what happens with a pure circle aperture.

Either Spiratone Portragon 100/4 or Spiratone YS 85/1.8. Neither has a
diaphragm.
