I also have a "next generation" laser collimator which much the sdame as the Seben. Same story, it was out of whack when rotated, I collimated it in the jig I made.
I wondered why my Cheshire and Laser would never agree with each other. This was why, but my additional reason was the focuser had it's own set of collimation screws too. Once I got all three to agree with each I was happy.
Unfortunately this seems to be a trait of the cheap laser collimators. You get what you pay for I guess. At least they have provision to collimate them to be useful again.
