The Atik 2" narrowband filter set 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). 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 2" narrowband 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.

The ATIK LRGB 2" filter set consists of Luminance, Red, Green and blue filters, that have been designed for CCD cameras to image deep sky objects, galaxies and stars in their natural colour. 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).

If a natural colour representation is what you want from you deep-sky imaging, an LRGB filter set should be your first choice. With OIII emission overlapping on the blue and green filters to allow high efficiency and natural colour imaging of all deep-sky objects. The gap between green and red filters serves to block out the light pollution line at 589nm and improves the colour of your images.

ATIK LRGB 2" Specifications

Transmission: Average 95%
Size: 2”
Coating Wavelength: 300-1050nm
Transmitted Wavefront RMS: λ/4
Parallelism (arcsec): 30s

SKU: ATK-0164
