I watched Ken's video, I think I have seen it before actually. All that is very straight forward.
I have some photos of what I am seeing through the tak scope. I have the "Tak Dot" centred, could maybe do with a whisker to the left? I can't see the light annulus through it unless I grossly miss-collimate the primary, so my reference is the secondary mirror baffle.
This is the procedure I followed originally, expecting a star test to look somewhat good, however, it showed a large error. This is where the conflict arose between the two methods, where really, it shouldn't?
