SVBONY SV240 telescope filter — multi-narrowband for astro photography
Multi-narrowband 2-inch filter for astro photography; blocks urban light and enhances Ha, OIII, H-Beta wavelengths. Noted for high transmittance and wide compatibility. Customer insight: strong contrast with minimal visual artifacts
Highlights
- multi-bandpass Ha/OIII/H-Beta coverage
- high transmittance in core wavelengths
- urban-light-pollution resistance
Pros
- high transmittance >90% in core wavelengths
- multi-bandpass covers Ha, OIII, H-Beta
- compatible with most astrophotography systems
- resistant to urban light pollution (Bortle 1–8)
Cons
- mixed value-for-money perceptions
- no dedicated filter replacement required may vary by system
- some customers mention no visual artifacts as a contrast note

Features
- 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.
