Chroma Filters OIII 36mm unmounted, 3nm (68953)

The narrowband OIII 3nm filter is designed specifically for nebula observation and astrophotography. It permits a narrow 3nm bandwidth of light centered on the 500.7nm wavelength, which corresponds to the OIII emission lines. By blocking all other light, this filter enhances contrast and reveals intricate details of nebulae, planetary nebulae, supernova remnants, and galaxies, making it an essential tool for deep-sky imaging.
