IDAS NBZ UHS(Ultra High Speed) versions

The IDAS Nebula Booster 48mm Filter is designed to enhance the contrast of Ha (Hydrogen Alpha) and OIII (Oxygen II) emission nebula while accommodating the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras, as well as mono-color astronomical cameras.

This filter has ideal flat-top bandpass, as well as in-band transmission. The off-center bandpass accommodates off-axis rays for fast optics (up to f/2). The steep bandpass edges help to minimize internal reflections. It is able to fully block NIR up to 1200nm.

Ideal for Ultra high speed optics such as RASAs and HyperStars
