Capture stunning images of hydrogen emission regions in nebulae with the ZWO Hydrogen Alpha (Ha) Filter. Designed with high-quality materials and anti-reflection coatings, this filter blocks all other wavelengths of light except for the Ha wavelength (656nm), enhancing contrast and detail in your astrophotography. The 2″ size is compatible with most telescopes and cameras, and the filter has a bandpass of 7±0.5nm FWHM. It is fine-optically polished to ensure accurate 1/4 wavefront over both surfaces, and has about 90% transmission at the H-alpha line (656nm). It has an infrared wavelength 700-1100nm cut-off and <0.1% transmission of off-band, OD3 (Optical Density). The filter comes in a protective case for safe storage.

Features:

  • Isolates the Ha wavelength (656nm) for enhanced contrast and detail in astrophotography
  • Blocks all other wavelengths of light for improved image quality
  • High-quality materials and anti-reflection coatings for excellent optical performance
  • Compatible with most telescopes and cameras
  • 7±0.5nm FWHM bandpass for precise filtering
  • Fine-optically polished to ensure accurate 1/4 wavefront over both surfaces
  • About 90% transmission at the H-alpha line (656nm)
  • Infrared wavelength 700-1100nm cut-off
  • <0.1% transmission of off-band, OD3 (Optical Density)
