SVBONY SV227 1.25" 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
SV227 1.25'' SII; H-Alpha; and OIII filters are narrowband filters commonly used in astrophotography and observations to capture specific emission lines from celestial objects
SV227 1.25" SHO Filter Kit are made with advanced glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength; or CWL
SV227 SHO filter set are used for deep sky photographic; 90% transmission of the filters can block the light pollution of the city; means the filter also blocks the light from mercury and sodium vapour lamps
In astrophotography and observation; using a combination of SV227 SII and H-Alpha and OIII narrowband filters can provide a comprehensive and visually appealing representation of celestial objects
