IDAS NBZEX 12 nm Ultra Narrowband Nebula Filter O-III, H-Alpha 2 Inch mounted

IDAS NBZEX-48 Dual Band Nebula Filter also for fast Telescopes and Camera Lenses

The NBZ filter is a dual line-pass filter that can be used with one-shot color cameras (DSLR, mirrorless system cameras, color astro cameras) and monochrome cameras. It supports all telescopes and camera lenses from f/1.8 and slower.

The NBZ filter lets the red H-alpha line and the blue-green [O III] lines through and increases the contrast. You get narrow band images with only one exposure series. The bandwidth is about 12 nm.

The special feature of the NBZEX filter is that it is also suitable for very fast optics from f/1.8. This allows you to use the nebula filter on virtually all common camera lenses and telescopes. The bandwidth of 12 nm is slightly larger for the NBZEX. This slightly larger bandwidth has the advantage that the filter can also be used on fast optics with similar contrast, without significant loss in transmission. So you don´t have to buy a special narrowband filter for fast camera lenses, the NBZEX can be used universally.
