OSLO How to input central obstruction?

Hello,

how can I input the central obstruction of a Newtonian to OSLO? I sucessfuly applied the 45 degree secondary, but this has no effect to the PSF.

A central obstruction should pump light from the center to the first diffraction ring. But my modelled secondary does not change that...

Thanx and
Gute Nacht
Tom
