SVBONY SV240 Telescope Filter, 2 Inches Multi-Narrowband Galaxy Nebula Filter, Ha OIII H-Beta Universal NIR Near-Infrared Light Pollution Filter for Astrophotography

SVBONY SV240 Telescope Filter, 2 Inches Multi-Narrowband Galaxy Nebula Filter, Ha OIII H-Beta Universal NIR Near-Infrared Light Pollution Filter for Astrophotography

• 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
