Future Optics Oxygen III (OIII) Filter - 36 mm Unmounted

Future Optics 36 mm OIII Filter


The Future Optics 36 mm OIII Filter increases contrast which enables the viewer to easily observe planetary & diffuse nebulae.

An Oxygen III filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae such as the Veil Nebula, as well as the Ring, Dumbbell and Orion nebula, among many others.
