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.
- Two filters made into one for maximum brightness
- Combines Fringe-Killer with Moon & Skyglow for Semi-APO contrast with refractors
- Non-ageing sealed coating edges
