Both Intes and Intes-Micro did, for all their Mak-Netwonians. They placed a precision circular metal aperture disk over the primary which also prevents it falling out of the cell.

 

Images don't show diffraction effects around bright stars - as commonly seen from scopes with exposed mirror clips, as well as the spikes from secondary spiders.
