How can it not be collimated correctly?
The only difference from it and most other telescopes, is that the secondary isn't held in four spider vanes, but on a hemispherical arc/vane.

Renato what is the appearance of the out of focus star image with no aperture stop on?
You are placing the test star very near the center of your eyepiece's field of view?
