• Cut-off depth ≥OD4; highly efficient in blocking urban light pollution or other background light; use this multi-bandpass filter for astrophotography in urban without traveling long distances to the suburbs;
• Compatible with 99% astrophotography systems; if you have different astrophotography systems, no need to prepare dedicated filters, one SV240 can meet your needs due to its high compatibility;
• Photoing more kinds of targets; SV240 multi-narrowband filter select Ha,OIII,H-Beta wavelength effectively can cover almost photoing needs;
• High transmittance; the >90% transmittance in core wavelength of Ha,OIII, H-Beta, more objects for your astrophotography by using this multi-bandpass filter;
• Multi-bandpass filters; without multiple filters' combination for colorful images; rich color in your lens;
• Resistant of BORTLE 8; the multi-narrowband filters can be resistant from Bortle 1 to Bortle 8 cities, suitable for almost all urban;
• 300-1100 mm working wavelength; the wider coverage of this multi-narrowband filter allows it to have a strong ability to tack light pollution.

Note: Optical filters that use infrared light often cause halos in the NIR region; which are exacerbated by the halos produced by the filter itself.

Professional 31.75 mm (1.25 in) narrowband H-Alpha astrophotography filter designed to capture intricate details of emission nebulae under heavily light-polluted skies.
