Atik 36 mm Narrowband Filter Kit

Designed with a 7 nm band pass to help capture every nebula photon while blocking a considerable majority of broad band light pollution, these Atik narrow band filters expose faint detail in nebulae and other deep sky objects by providing a much higher signal to noise ratio. This Narrow Band Filter Set consists of three 36 mm unmounted filters - Hydrogen-Alpha (Ha), Sulphur (SII), and Oxygen (OIII).

Suitable for use with any Atik filter wheel, these filters allow astrophotographers to capture deep-sky objects in spectacular narrow band. In fact, these filters are frequently used to image objects in the Hubble palette.
