The NB2/NB3 filters are dual line-pass filters which 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 for the NB2 and the red SII and the blue-green OIII lines for the NB3, these filters enhance 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 which provides IR blocking is required in combination with this filter.

  Emission Lines Filter Sizes Base Filter
NB1 Triple - Hβ+OIII, Hα 48mm & 52mm None required
NB2 Dual - OIII, Hα 48mm, 52mm, Canon Drop-in Required*
NB3 Dual - OIII, SII 48mm, 52mm, Canon Drop-in Required*

  * In-camera IR blocker works as the base filter.
