Diffraction spikes don't need a high quality lens, but lenses won't give them when used wide open which is often desirable in low light.First, I'm a film shooter. I have never used a filter for "protection". I use specialty filters once in awhile (polarizer/star etc.) or colored filters when shooting BW. But a sturdy metal lens hood has saved the front of my lens a few times.
In regard to the star filter, you should never need one. A high quality lens will do this anyway. Example of this below. No filter. Shot in Madrid, Spain...
