Atik Narrowband 1.25″ Filter Kit

The Atik narrow band filters are manufactured with a band pass of 7nm, capturing a nebula’s photons while preventing a large portion of the broad band light pollution from entering. The result is a much higher signal to noise revealing faint details in nebulas. The Narrow band filter set comprises of Hydrogen-Alpha (Ha), Sulphur (SII) and Oxygen (OIII).

Oxygen III 500.7nm 7nm >80% Maximum<0.3% Average 0.1%
