Product description

The new generation of Baader filters is characterised by:

  • Reflex-Blocker™ coatings for maximum insensitivity to retro-reflection from nearby auxiliary optics, even under the most adverse conditions
  • Identical filter thickness to existing standards, with the utmost care taken to ensure homofocality (parfocal)
  • Blackened edges all around, with filter front indicator in the form of a black outer edge on the telescope side to prevent any reflection from light falling on the filter edge
  • Each filter individually precision-polished and coated, with sealed coating edge (NOT cut from a larger plate – with exposed coating edges, see here for more information)
  • Life-Coat™: Harder coatings to enable an age-resistant coating with an unlimited service life – even in the most adverse environments!
