The NB3 filter is a dual line-pass filter which can be used with one-shot color (OSC) cameras such as DSLR's or astronomical OSC cameras.
Passing the red SII and the blue-green OIII lines, the NB3 filter enhances the contrast of these 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 NB3 filter.Features:
- Dual-band for OIII and SII
- 52mm and 48mm sizes
- IR blocker as a base filter required
- Made in Japan
