ZWO LRGB 36mm Filters

The ZWO LRGB  36mm filter has better transmission, better coating,  better color separation

the RGB color combine weights will be approximately 1:1:1

  • Fine-optically polished to ensure accurate 1/4 wavefront
  • more than 92% transmission at passband
  • Infrared wavelength 700-1100nm cut-off
  • Precision off-band blocking
  • Multi-layers anti-reflection coating
  • Small spectral “gap” to minimize effect of light pollution
  • More parfocal – thickness  2mm

ZWO OIII 36mm Unmounted Filter

OIII, or doubly ionized oxygen, emits light in the blue/green, or teal portion of the spectrum near 500 nm. Planetary nebulae and supernova remnants emit most of their light in the OIII line.

ZWO H-a 36mm Unmounted Filter

Hydrogen-Alpha is the most dominant emission line in star-forming regions. H-Alpha light is created by atomic hydrogen, and is responsible for the red color seen in most nebulae.

ZWO SII 36mm Unmounted Filter

Sulfur is in the deep red of the spectrum near 672 nm. When combined with H-a and OIII, these three filters will produce images with colors that are reminiscent of those taken by the Hubble Space Telescope.

These ZWO 36mm filters are unmounted. ZWO narrowband filters are fine-optically polished to reach an accuracy of 1/4 wave. Their performance is further enhanced by multiple layers of anti-reflection coatings.
