So I went right back to the secondary positioning in the focus tube, using a collimation cap, and found it was too far left and at too much of an angle (both rotation and tilt). After a while I managed to get it right in the center.
Then I did the laser collimation again and aligned secondary to primary and primary to secondary. And finally I checked with the chesire and I could see what the second image was displaying, the "fast" offset in collimation, being that it's F4.9.
Last step will be star test and hope everything lines up!
