Sharper Nebula Imaging
Featuring a 7nm FWHM bandwidth and Tavg ≥88% transmission, it precisely isolates key nebula emission lines while blocking over 99.999% of unwanted light (OD5). With its wide 300–1000nm cut-off range, this filter delivers exceptional light pollution resistance and a higher signal-to-noise ratio, ensuring crisp, high-contrast deep-sky images even under city skies.
Combination
The SV220 1.25" SII + OIII 7nm Dual-Narrowband Nebula Filter is compatible with the following components: SV550 Telescope(not included), SV209 Field Flattener(not included), SV226 Telescope Filter Drawer(not included), M42 to M28.5 Adapter (not included), SV405CC Cooled Camera (not included).
