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
This UV/IR Cut off filter blocks undesirable ultraviolet and infrared rays that may interfere with obtaining the high contrast and quality images possible with a digital sensor
It serves as a permanent lens protector;digital imaging with DSLR cameras;CCD cameras;and modified WebCams;or telescope
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. The UV-IR-Cut filter uses the very latest coating technology to deliver the high filtration quality and lifetime durability. The UV-IR cut filter combine with any of the other Baader filters screws into the back of the eyepiece or camera adapter to block out the chromatic aberration unwanted. So it delivers the sharper images possible; it can also reduce the ghost images caused by IR radiation.
