The NB2 filter is a dual line-pass filter that can be used with one-shot color (OSC) cameras such as DSLR's or astronomical OSC cameras.

Passing the red Hα and the blue-green OIII lines, the NB2 filter enhances the contrast of the dominant lines found in emission nebulae without the time-consuming use of single-band filters. The resulting images can be used for luminance contrast enhancement of traditional RGB-balanced images or creation of images in various popular false-color palettes.

Note that a base filter that provides IR blocking is required in combination with this filter.

The NGS filter provides the IR blocking required for using the NB2 filter.

  • Dual-band for OIII & Ha
  • 52mm & 48mm sizes
  • Made in Japan
  • IR blocker as a base filter required
