The SII 5nm 2" filter from SVBONY is an essential accessory for any astrophotographer looking to capture high-quality images of deep-sky objects. This filter allows for the transmission of an extremely narrow bandwidth of 5nm centered at 672nm, which is ideal for observing sulfur hydrogen emissions in nebulae.

"Designed to block infrared wavelengths from 700nm to 1000nm, this filter eliminates the need for a separate IR-Cut filter. It screws directly into the 2-inch barrel of your telescope's eyepiece, making it simple and effective to use. Thanks to its high-performance design, the SVBONY SII filter also reduces transmissions of other wavelengths, including those responsible for light pollution, allowing for an enhanced viewing experience with monumental contrast."
