The other image shows either tracking issues (need to see the ENTIRE image), flexure/sag/tilt or a not-flat field. Some reducers do NOTHING to mitigate field curvature, whereas some of the better, more expensive ones both flatten and reduce. Show the entire shot, including all corners, and this can be nailed down more

Thanks Lewis.
Might need to invest in a better reducer in the future.
I think I might have had some slight tracking issues which I am trying to iron out with an OAG.
