In my case getting rid of all the glass layers between the MPCC and the CCD helped. I've never tried inserting a filter between the two though. My filters have always been after MPCC at the end of the imaging train. You might try it. But I'd suspect any filter with a mirror like surface such as Ha for example would make things worse as it would reflect the back of the MPCC onto itself.
