I really hate that you can see artifacts from the hex mirrors.
Three struts, but because of light diffraction, six spikes.
There are much smaller diffraction effects which are in part due to the mirrors, but these are far smaller and not immediately evident. Both apply largely to foreground point sources, which is to say, relatively nearby stars. Distant objects with an appreciable size don't produce diffraction spikes.

Of course, the JWST without its struts and its mirrors wouldn't be much of a telescope! So the diffraction spikes are a part of doing business and also have the helpful side effect of allowing us to quickly know which objects are stars vs galaxies, since only the former have the really prominent spikes.
