Atik 2" 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 2" filters - Hydrogen-Alpha (Ha), Sulphur (SII), and Oxygen (OIII).

Each filter in this set is compatible with Atik's filter wheels. Astrophotographers will be able to capture deep-sky objects in spectacular narrow band with these filters, which are frequently used to image objects in the Hubble palette.
