The SVBONY H-Alpha is an extremely narrow emission-line filter that works by allowing a 5nm bandwidth of light, centered on the 656.3nm wavelength through, and blocking the transmission of contrast-killing light pollution wavelengths. Wavelengths that are responsible for natural light pollution, or skyglow, are drastically reduced, as is 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.

Please Note: This OIII filter is NOT for use on the Sun, and also unsuitable for telescopes with a focal ratio below F/5. 

The SV229 is an ideal choice for viewing the sun, and it conforms the standard ISO 12312-2: 2015. You can use it with confidence. It can provide a clear, crisp sunspots, solar eclipses, granulation through telescopes and binoculars view while rejecting harmful ultraviolet and infrared radiation. The sun will appear in a natural orange color when viewed through your telescope using this Solar filter. SV229 solar filter is a must-have item to observe the sun without damaging your eyes - optical filter fits snugly over your telescope's aperture.

The SVBONY Narrowband OIII filter is designed for nebula observation allowing 5nm bandwidth of light centered on a wavelength of 500.7nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high- and low-pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.

Please Note: This OIII filter is NOT for use on the Sun, and also unsuitable for telescopes with a focal ratio below F/5. 

The SVBONY Sulful II Extra Narrowband Filter transmits a 5nm bandwidth of light that is centered at 672nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution. This SII filter blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter. Due to the narrow bandwidth and high transmission rate of this filter, you will experience a major boost to contrast.

Please Note: This OIII filter is NOT for use on the Sun, and also unsuitable for telescopes with a focal ratio below F/5.
