Askar 2" Colour Magic C1 (Ha/OIII) and C2 (SII/OIII) Duo Band Filter Set

The Askar C1 is a Duo Band Filter passing the Ha and OIII wavelengths. It can be used in isolation with Colour Cameras or in combination with the C2 SII and OIII Duo Band Filter to provide a superior method for achieving the SHO (Hubble Pallet) narrow band colour balance with colour imaging cameras.

The Colour Magic C1 Duo-band filter (Hα+OIII) has a high transmission of over 90% at its centre wavelength (500.7nm and 656.6nm). It can effectively improve the quality of the image by making the sky background of the image darker while maximising contrast throughout the image and enhancing the contrast of your pictures, thus making it easier to display the details of the stars.

The Askar C2 is a Duo Band Filter passing the SII and OIII wavelengths. It is designed to be used in combination with the C1 Ha and OIII Duo Band Filter to provide a superior method for achieving the SHO (Hubble Pallet) narrow band colour balance with colour imaging cameras. The C2 SII and OIII Filter provides the missing band data so that owners of colour cameras can achieve the SHO colour balance in their narrow band images.

The Colour Magic C2 Duo-band filter (SII+OIII) has a high transmission of over 90% at its centre wavelength (500.7nm and 672nm). It can effectively improve the quality of the image by making the sky background of the image darker while maximising contrast throughout the image and enhancing the contrast of your pictures, thus making it easier to display the details of the stars.

In areas with very serious light pollution, these filters can also selectively filter light pollution.
