The ZWO Ha, SII, and OIII 7nm narrowband filters are specially designed for astrophotography, allowing for the creation of "Hubble-like" quality images. By selectively reducing transmitted wavelengths, these filters eliminate the effects of street lighting and the Moon, providing high contrast for many nebulae.
- Bandwidth: FWHM 7nm (+/-0.5)
- 90% transmission on the Ha/S-II/O-III lines
- Cut-off in the infrared (700/1100nm)
- Schott glass
- Glass thickness: 1.85mm
- Precise optical polishing for a wavefront at lambda/4 and a flatness <30" arc on both surfaces
- Double-sided optical coating with anti-reflective treatment
- CNC machined aluminum cell construction
- Available in 4 formats: 31.7/50.8mm eyepiece and unmounted 31mm/36mm circular
