Svbony 7nm Dual-Band Nebula Filter Ha & OIII

  • Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted
  • Take color images without needing to combine images with multiple filters
  • Useful for imaging emission nebulae, planetary nebulae and supernova remnants
  • Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow

SV220 Dual-Band 7nm Nebula Filter

  • Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted
  • Allows for imaging in bright man-made light pollution and moonlit conditions
  • Take color images without needing to combine images with multiple filters
  • Most useful for One-Shot Color cameras
  • Useful for imaging emission nebulae, planetary nebulae and supernova remnants
  • High transmission and sharp cut-off can greatly enhance the contrast and bring out the most detailed information for those deep-sky objects
  • Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow
  • The duo-band narrowband filter is not suitable for visual observation and not designed for imaging or observing the Sun
  • Be aware that the SV220 is not a great fit for fast telescopes, some users reported that the Duo-Band OSC Filter paired with the RASA caused band shift, thus clipping the HA data.
