How can i be sure that they are not twisted, even slightly? Is there a method?

As i can see by eye they are not...

Hello again,

i've noticed that around bright stars the diffraction spikes appear to split in two (for example my m45 pic, page 31).

How can i fix that?

I've tried to align the spider vanes perfectly and i think i've done it but the problem remains...

I have the 150 quattro I upgrade it with a new spider and primary mirror  mask this is a much stronger one and the mask removes the reflection from the main mirror clips.i got mine from Backyard Univers,it cost me 220€ inc postage.
