Askar 2" Colour Magic C1 Duo Band (Ha/OIII) Filter

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.

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

Looks well made for money
18 February 2024  | 

Filter arrived in nice protective case, coatings on glass look good with no imperfections visible and threads well machined offering a solid fit in filter holder.Obviously the test will be at first use but looks promising so far for a good intro into narrowband imaging.
