About this product
Part Number: ATK0176P
The Atik narrow band filter are designed with a band pass of 7 nm to aid in capturing all a nebula’s photons while the vast majority of the broad band light pollution is stopped. 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).
The SHO narrow band filter set is compatible with our filter wheels and allows astrophotographers to capture deep-sky objects in spectacular narrow band. This filter set is commonly used to image objects in the Hubble pallet.
