Atik 1.25" narrow band filter set
Atik 1.25" narrow band filter set. This narrow band filter set is designed with a 7 nm bandpass to help capture all the photons in a nebula while the vast majority of the broadband light pollution is rejected. The result is a much higher signal to noise ratio that reveals faint details in nebulae. deep sky.

Atik 1.25 "mm narrow band filter set.
The Atik narrow band filter set is designed with a 7 nm bandpass to help capture all the photons in a nebula while the vast majority of the broadband light pollution is rejected .The result is a much higher signal to noise ratio that reveals faint details in nebulae and deep sky objects. The narrowband filter set includes hydrogen-alpha (Ha), sulfur (SII) and oxygen (OIII) filters.
The narrowband SHO filter set is compatible with Atik filter wheels and allows astrophotographers to capture deep sky objects in a spectacular narrow band. This filter set is commonly used to image objects in the Hubble palette.
