Product description

The bandpass / L filter is suitable for aperture ratios from f/15 to f/1.8

The filter

  • reflects harmful heat radiation in the infrared spectral range
  • provides 98% transmission across the entire visible spectrum
  • Prevents blurred star images with red-sensitive cameras

Baader's CMOS-optimised filters are characterised by:

  • increased contrast
  • narrower half-widths (FWHM)
  • Reflex Blocker™ coatings for maximum insensitivity to retro reflection from nearby auxiliary optics, even under the most adverse conditions
  • FWHM carefully designed for each filter category to enable 1:1:1 exposures, matched to typical CMOS quantum efficiency and signal-to-noise ratio
  • Identical filter thickness to existing standards, with the utmost care taken to ensure homofocality
  • Blackened edges all around, with filter front indicator in the form of a black outer edge on the front to additionally prevent any reflection from light falling on the filter edge
  • Each filter is individually precision-polished and coated, with a sealed coating edge (NOT cut from a larger plate with exposed coating edges)
  • Life-Coat™: even harder coatings to enable an age-resistant coating with an unlimited service life – even in the most adverse environments

This new CMOS-optimised filter generation is designed to become the new standard in amateur astronomy.
