Hi Lee. I have a similar setup with Astronomik filters - no halos at all with RGB. Had one slight halo around a very bright star with an Astronomik Ha filter, but nothing more than a very minor cosmetic problem - had to look hard to pick it.
Maybe there are batch problems with the filters if you and Peter have had issues?
