ColourMagic C1 H-Alpha and OIII Duo Band Features

  • The Askar 2" ColourMagic C1 Duo Band Ha/OIII Filter is geared for color camera users.
  • Includes an H-Alpha/OIII filter to isolate the narrowband emission lines of 500.7nm and 656.6nm respectively in deep sky objects, and in particular emission and planetary nebulae.
  • Narrowband filters restrict bandpass to specific emission lines, enhancing detail in deep sky objects as well as effectively reducing the impact of light pollution, making cosmic imaging more viable in light-polluted areas.

Enhances H-Alpha and OIII Emission Lines

For imagers with a color camera, the Askar 2" ColourMagic C1 Duo Band Filter consists of an H-Alpha/OIII filter which filters out consistent narrowband emission lines of 500.7nm and 656.6nm that are often found in most deep sky objects, and in particular emission and planetary nebulae. 

Since the filter is considered narrowband, thus only allowing a bandpass within a specified emission line, it helps generate more detail in deep sky objects as well as to an extent, removing the effects of light pollution making imaging the cosmos more suitable and obtainable in light polluted areas.

The following filter specifications are as follows:

  • The full width half maximum (FWHM) of the H-Alpha approximately 15nm while the OIII is 35nm.
  • The filters have a measured light transmission of approximately 90%.
  • 2mm thickness.
