IDAS NBZEX-48 Dual Band Nebula Filter NBZEX-48 also for Telescopes and Fast Camera Lenses
The NBZ filter is a dual line-pass filter that can be used with single-capture color cameras (DSLRs, mirrorless cameras, color astronomy cameras) and monochrome cameras. It is compatible with all telescopes and camera lenses from f/1.8 and slower.
The NBZ filter lets through the red H-alpha line and the blue-green lines [O III] and increases contrast. You get narrow band images with only one series of exposures. 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 12 nm bandwidth is slightly wider for the NBZEX. This slightly wider bandwidth has the advantage that the filter can also be used on fast optics with similar contrast, without significant loss of transmission. So you don't need to buy a special narrow band filter for fast camera lenses. The NBZEX can be used universally
