SVBNOY SV227 SII / H-Alpha / OIII 5nm 2" Narrowband CCD Filter for Deep Sky.SII, H-Alpha, and OIII filters are narrowband filters commonly used in astrophotography and observations to capture specific emission lines from celestial objects.
In astrophotography and observation; using a combination of SII; H-Alpha; and OIII narrowband filters can provide a comprehensive and visually appealing representation of celestial objects.
Each filter of the SII, H-Alpha, OIII is individually tested and scanned to ensure that the quality meets the high-performance parameters
Solar Observing and imaging Visual observation do not look at the sun with the filters; serious eye damage will result if you fail to observe the warning.
Conventional narrowband filters cause a heavy loss in transmission due to the strong center wavelength (CWL)-shift; our filter can guarantee high transmittance.The folters are used for deep sky photographic and all are NOT for use on the Sun.
- 90% transmission of the filters can block the light pollution of the city.
- Filter threads directly into the 2 inch barrel of your telescope eyepiece.
- 90% transmission means the filter also blocks the light from mercury and sodium vapour lamps.
- Standard M48x0.75 thread interface.
- The thickness of the filter can affect wavelength and dispersion of the filter.
- The filter can use with filter drawer and electronic camera.

Introduce
This SII filter blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter.
300-1000nm wavelength range; the SVBONY SII 5nm 2" Filter transmits a 5nm bandwidth of light that is centered at 672nm.
2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece.
SVBONY SII narrow band filter reduces other transmissions; including wavelengths of light that are responsible for light pollution (both artificial and natural).
The narrow bandwidth and high transmission rate of this filter will make you experience a major boost to contrast.
Please Note: This SII filter is NOT for use on the Sun.
SVBNOY H-Alpha 5nm 2" Filter blocks the transmission of contrast-killing light pollution wavelengths; improve contrast and detail.
The filter blocks the infamous artificial light pollution caused by high- and low-pressure sodium vapor and mercury vapor lights.
This H-Alpha filter also blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter.
Allowing 5nm bandwidth of light centered on a wavelength of 656.3nm to pass through; 90% transmission.
Astrophotography under a light-polluted night sky can be difficult; the solution is an H-alpha filter; the H-alpha cut-off filter works to filter out a large part of this light pollution.
Please Note: This h-alpha filter is NOT for use on the Sun.
SVBNOY OIII 5nm 2" Filter greatly enhances contrast and allows high-contrast imaging even in areas with strong light pollution.
OIII 5nm 2" Filter is designed to deliver 90% transmission at the 500.7nm line which provides you with the maximum signal and well defined nebulae structures.
300-1000nm wavelength range; the SVBONY OIII 5nm 2" Filter transmits a 5nm bandwidth of light that is centered at 500.7nm.
2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece.
SVBONY OIII narrow band filter reduces other transmissions; including wavelengths of light that are responsible for light pollution (both artificial and natural).
Please Note: This OIII filter is NOT for use on the Sun.
