SII, H-Alpha, and OIII filters are narrowband filters commonly used in astrophotography and observations to capture specific emission lines from celestial objects
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
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
