Semi APO Filter
1.25 inch
#2458398


Combination of "Neodymium Moon & Skyglow" and "Fringe Killer" Filters Time and time again we were made aware of customers who were combining our Neodymium Moon and Skyglow filter with our Fringe Killers to deliver amazingly colour-corrected images to achromatic refractors. This combination however did produce refelctions.

After analysing these reports we developed our Baader Semi-APO filter with IR blocker, a reflection-free combination of the Moon & Skyglow with a stronger coating of the Fringe killer. This result was a virtually colour-neutral image without the blue and red halos (violet fringing) and an increase to image contrast.
