chromatic aberration? spherical aberration? too much angular resolution? jittery images caused by strong stratospheric winds?

Spherical Aberration. It made the HST myopic. When HST was designed, it was supposed to have a resolution of 0.1 arcseconds. It's actual resolution was 1 arcsecond. After the corrective lens was installed, the repaired HST now has a resolution of 0.05 arcseconds which is very, very good and better than the design specification.

Spherical aberration. The mirror did not have the correct curvature. They chose not to perform a test on the mirror to save money. They had to build corrective lens to be installed while in space to correct the problem.

Spherical aberration.
The mirror was not ground correctly.

It suffered from being designed by bureaucrats and being built by the lowest bidder.
