Average OD5: SV220 3nm Dual-Narrowband Filter offers a wide cutoff range of 300-1050nm; its transmittance is as low as 0.001%; effectively suppressing stray light and light pollution; improving signal-to-noise ratio for more detailed images
Minimal halo coating design: the 3nm H-Alpha and O-III Narrowband Filter features a minimal halo coating that reduces glare; ensuring sharp; detailed imaging of celestial objects with enhanced contrast; color accuracy; and reduced light pollution
85%+ transmission rate: the SV220 3nm H-Alpha and O-III Narrowband Filter offers high contrast and detailed imaging; enabling fast capture of deep-sky objects even in heavily light-polluted cities
Ideal for imaging a wide range of deep sky objects; including galaxies; reflection nebulae; emission nebulae; and star clusters; under skies ranging from Bortle 1 to Bortle 8
Multi-narrowband design allows for effective astrophotography even in heavy light pollution or moonlit conditions
Description
SV220 H-Alpha and O-III 3nm Dual-Narrowband Filter enhances astrophotography by reducing stray light and light pollution, suitable for capturing deep-sky objects. The SVBONY filter is a better choice for all digital imaging with digital cameras; DSLR camera; CCD cameras; modified Webcams and telescopes. SVBONY SV240 1.25‘' Multi-Narrowband Filter: Your Urban Deep-sky Astrophotography Key! Cuts light pollution, boosts Ha/OIII/H-Beta signal for stunning contrast & detail. Shoot galaxies, nebulae & clusters under any sky, Bortle 1-8 or moonlight. SV240 can be seen as the combination of SV220 and UHC filters, and has remarkable performance both in narrowband and broadband targets.
