First of all it isl an effective light pollution filter. My suburban sight is a notch less dark than my dark sight and notch better than my suburban sight. Star images are crisp and more pinpoint although the fainter stars seem to be dimmer. DSO seem to have more definition because of the contrast of this filter. Only very slight light loss on these. A gentle but effective filter with some light loss. Didn't notice yellow coloration. Mars only 7 arc seconds went from a blob to a disc with turbulence no visible surface details at this distance although hints showed. I don't have much CA on my 6 inch SCT but around the moon it was eliminated when I moved my eye a certain way.

I'm happy with the results I gotten with the filter. I have taken pictures of the Sun, moon and Jupiter and I can see the quality of the pictures much better. I also used to take landscape pictures and I also see better color and not the yellow edges that it had before... definitively an improvement

The Baader Semi APO Filter 1.25" delivers an amazingly neutral view, while cutting most of the annoying and contrast-robbing violet fringe that plagues all achromats. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon & Skyglow Neodymium substrate. The result is similar performance to the Fringe Killer + Moon&Skyglow combination, but with a slightly stronger violet cut. It's high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast and aesthetics are remarkable, even with small refractors. The RGB enhancement of the Neodymium substrate actually boosts color contrasts, particularly for Jupiter and Mars.
