Thanks for the suggestion. In this particular fractal the thin lines are especially a problem which is due to thickness variable on glynsimm3 not working right on the version of apo I was using. I think erelex used apojk when doing this plugin so I will try that to see if the thickness works there. One pixel thick lines are very often hard to rid of that pixel look. Overlaying it with a thin julian ring might also do the trick. Might be worth going back and refinning that.
