The Baader color filters are carefully made for amateur astronomical purposes. The glasses are finely polished optically . 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 features of the Baader filter:

  • 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

Dark blue bandpass filter 435nm: filter for visual and photographic planetary observation

  • Better detection of the phase design of Venus
  • The violet clearing on Mars is easier to see
  • To observe the large red spot on Jupiter, enhances the contrast between the bands and zones on Saturn
