Observe rings, clusters, and nebulas in high clarity by using the Celestron Oxygen III Narrowband Filter with your telescope. By filtering and isolating ionised-oxygen lines emitted by planets and nebulas, this filter offers clear and contrasting visuals. It further blocks the visual spectrum from 400 to 700 mm by utilising its vacuum-deposited coating, eliminating halos that form behind stars.
