Focuser Position!!!!!!  So it is pretty evident that the under/over correcting was being caused by the Baader filters, as the Chroma work fine with the EL Panel, this is the blue calibrated stack now

What do you mean with that? Did your focuser move so the telescope was unfocused when taking the flats? If yes, how much was it moved?

@stastro That is awesome! So your filter gamble paid out. I now wonder if you get any word back from Baader regarding this.

Well I sent an email to Thomas Baader, copying in my reseller, and guess what.....no reply, my reseller even copied in Lee Sproats, again no reply.  It seems that Baader's attitude is "This is how it is, so live with it"

Mmm, that's not good indeed. I had the OIII issue with huge halos, apparently also a batch issue. It's not great advertisement for sure.
