Had some more time with it under the stars last night.
Once again the ES 14mm and 30mm were suburb. Still haven't figured out the best position for the 9mm. It is quite possible I have found the best position and I'm not satisfied with it. It is also possible that the coma corrector has removed the coma and flattened the field and has now revealed an eyepiece aberration I could not see before as a coma corrector does not actually correct the eyepiece itself.
