The stars in the corners appear like little arcs is what I am referring to.

Thanks Paul
A tilt adjuster has just arrived from Bintel. It is 11mm,so if I add a 10 mm spacer (as Rod suggested) to the 294 that will make 27.5. I will give that a go next clear night.
I am not sure what the problem was with the 283. That was the first time I used it on the Rasa. It wouldnt screw all the way on the Starizona filter holder , so it wasnt 26mm. But I cant see why that would cause a tracking problem
cheers
