ZWO H-alpha 7nm Filters

The ZWO  H-Alpha filter  has a bandpass of  7nm and passes light at 656nm  wavelength, light transmission rate comes up to 80%. Best choice of narrowband H-alpha astrophotography filter for high-contrast imaging and revealing rich details of the nebula even in areas with strong light pollution, just prepare to experience the infinite fun with it !

  • Hubble look of images can be made by the combination of H-alpha, OIII-CCD and SII-CCD, such as the famous “Pillars of Creation” (M16 Eagle Nebula)
  • Narrowband imaging with SHO set (H-alpha, OIII-CCD and SII-CCD) can be done with the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks
  • H-alpha filter is the first narrowband addition to LRGB set for most imagers who blend a black-and-white Ha image into RGB data to enhance structural detail while maintaining natural look

ZWO H-alpha 7nm filter

The ZWO H-alpha 7nm filter is centered around 656.3nm. H-alpha is the most abundant emission line in all nebulae, emitted by atomic hydrogen which makes up about 92% of the universe. The narrow bandwidth of H-alpha will remove all light pollution increasing contrast of the H-alpha emission lines seen in most nebulae.

When used in conjunction with the narrowband OII and narrowband SII filters they make up part of the Hubble palette, used by HST to image these and other elements in nebulae.

Available in 1.25 inch, 31mm unmounted and 36mm unmounted.
