Hey H0ughy,
I have the Baader Fringe Killer I use it on my 90mm F6.6 refractor.
I'd say (in my very newb opinion) that it works good, however, and it have read this elsewhere too, it puts a yellow tint on objects, most noticably the moon.
Now, I also have a Baader Moon and Skyglow filter, when I use both that and the Fringe Killer the yellow tint goes away as does the CA, albeit with a little less light transmission.
I find that I only use the Fringe Killer on really bright objects (venus, moon..) at magnifications of ~100x on my scope, and when I use the fring killer I typically end up always using the Moon and Skyglow filter in conjunction with it as well, but since the objects are bright the reduced tranmittence is not a problem.
So I guess the moral of the story:
Bright object = CA
with Fringe Killer = Yucky yellow tint (IMO) but "no" CA
with Fringe Killer + Moon & Skyglow = Natural colouration and no CA.
I say "no" because one could argue that the yellow tint is a Chromatic Abberation... though not one caused by out of focus light.
Hope this helps !!
