90% transmission of the filters can block the light pollution of the city. Filter threads directly into the 2 inch barrel of your telescope eyepiece. 90% transmission means the filter also blocks the light from mercury and sodium vapour lamps. Standard M48x0.75 thread interface. The thickness of the filter can affect wavelength and dispersion of the filter. The filter can use with filter drawer and electronic camera. The Narrowband filter is designed for nebula observation. Package Includes: 1x SVBNOY 2" OIII 5nm 1x SVBNOY 2" H-Alpha 5nm 1x SVBNOY 2" SII 5nm 3x PP Material Plastic Box

  • SV227 2" Narrow-Band Filter is specifically designed for use with monochrome cameras in astrophotography; it effectively isolates the emission lines of certain celestial objects; enhancing image detail and contrast to make features more pronounced
  • SII, H-Alpha, and OIII filters are narrowband filters commonly used in astrophotography and observations to capture specific emission lines from celestial objects
  • Each filter of the SII, H-Alpha, OIII is individually tested and scanned to ensure that the quality meets the performance parameters
  • Conventional narrowband filters cause a heavy loss in transmission due to the strong center wavelength (CWL)-shift; our filter can guarantee transmittance
  • 2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece
  • In astrophotography and observation; using a combination of SII; H-Alpha; and OIII narrowband filters can provide a comprehensive and visually appealing representation of celestial objects
