The CHROMA TECHNOLOGY OIII (8nm) Filter is a versatile narrowband filter crafted for astrophotography and scientific imaging. Designed to isolate the Oxygen III (OIII) emission line at 500.7nm with an 8nm bandwidth, this filter provides excellent contrast while allowing more light throughput. It’s ideal for capturing stunning deep-sky images, particularly of nebulae, even in light-polluted or moonlit conditions.
Featuring advanced multi-layer dielectric coatings, the CHROMA OIII filter ensures outstanding performance and durability. Its design minimizes halos and reflections while maintaining superior transmission, making it a reliable choice for astrophotographers of all levels, whether working in urban skies or dark-sky locations.
