I can see from the final registax image that the collimation is almost spot on. Could do with a very minor adjustment. Move central obstruction down and to the right, which would see the airy disc shift up and to the left to a perfectly centred position.
I think that's right?

looks pretty close to me Matt.At this mag you should be closer to focus to pick up collimation error better - that is smaller rings
