Take advantage of our special offer. Get 50% off any filter set (or both filter sets), when you buy any Atik mono camera (with the exception of the Atik GP).
The Atik Narrowband 36mm 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.
