OK, I bought a new T adapter (2 inch as opposed to the 1.25 that I had) and a Bahtinov mask.
Sad to say, only a slight improvement
I can get the centre spike in the middle of the x no problems, but the resulting image is still not sharp.
Also, visually, the same issue as before, you focus from blurry one side of focus, to blurry the other side of focus, but it never gets sharp in the middle of the two, just less blurry.
Imaging train is now, Telescope, direct connect T adapter, Canon T ring, DSLR
This is the T adapter that i have:
