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
