The Baader color filters are carefully manufactured for amateur astronomical purposes. The glasses are plane-optically polished . These filters far exceed the quality of the usual, "raw polished" (= hot flamed) colored glass filter.

Thanks to the fine-optical polishing, these filters can be used anywhere in the beam path - far before the focal point (e.g. in front of a binocular approach!) Without causing optical errors (astigmatism) or otherwise deteriorating the image in any way!

Other special properties of the Baader filters:

  • Elaborate frame with the largest possible free opening to prevent vignetting
  • CNC-milled "handle crown" - offers excellent handling convenience
  • 7-layer anti-reflective coating on both sides with only 0.25% residual reflection per surface

Yellow long pass filter 495nm: Suppresses the secondary spectrum (blue component) in achromatic and semi-apochromatic refractor lenses and thus increases the image sharpness!

  • The contrasts of the moon and Mars surfaces are increased
  • The filter also increases the contrast between the bands and zones of the Jupiter clouds
  • For larger instruments with an opening of 8 inches or more (200mm) details can be seen on Saturn.
