CCD Inspector analysis of the OIII MasterFlat frame after flipping the entire filter wheel assembly to reverse the orientation of the filters relative to the OTA vs. camera. The interference/diffration/reflection issue has improved significantly with a substantial reduction in variation in intensity. There is still some residual vignetting and the concentric ring pattern seen in the stretched flat.
