I have got a reply from another David on this forum (David Dells..yahoo ED127 forum that is) who had a similar issue but the flare was not as bad as mine. He has adjusted his to an acceptable level of concentricity.
I asked him if this adjustment had an effect on his star diffraction pattern before or after. ...aka what was his diffraction pattern before & after wrt the aberration. Still awaiting a reply.
