How to collimate refractor?

Hi,

I have 102x1000 Skywatcher refractor on EQ3 mount that I recently bought here.
I removed diagonal, checked collimation with laser and the red dot was away from centre quite a bit?

Star test shows concentric circles both ways?
I removed dew shield but can't see any adjusting screws as some people suggest on the net? On the other end where the focuser is, there is nothing to be adjusted either? I can unscrew the focuser and corrected it a bit but still out from centre. And it gets worse with diagonal in and then laser.

Is there any way to collimate this scope?

cheers

bob
