SVBONY SV227 2" SHO Telescope Filter Set, Narrowband Filter Kit, SII H-Alpha OIII 5nm Narrow-Band Filters, Reduce Light Pollution, 3Pcs Set for Emission Nebula Planetary Nebulae Astrophotography

• 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
