Baader H-alpha Ultra-Narrowband-Filters (3.5nm) – CMOS Optimized

Baader H-alpha Ultra-Narrowband-Filters (3.5nm) – CMOS Optimized

Highlights

  • Baader H-alpha Ultra-Narrowband Filter – Premium Grade
  • 3.5 nm FWHM (to harmonize the exposure time with O-III / S-II), recommended for optical systems from f/10 to f/3.5
  • For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
  • Reflex-Blocker™ hard coated and Plane-optically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black front side outer rim
  • Optimized for modern CMOS cameras, but excellent for CCD camera technologies

We explicitly warn against observing the sun with a DeepSky 6.5 nm (equivalent to 65 Angstrom) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Angstrom. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!

This new generation of Baader CMOS-filters features:

CMOS-optimized Baader Filters

 

  • Increased contrast
  • Ever more narrow band-passes
  • Reflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
  • FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
  • Identical filter thickness to existing standards, with utmost care for remaining Par focal
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black front side outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
  • Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)
  • Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
