IDAS NBX Nebula Booster Dual-Band Filter Review

The IDAS NBX Nebula Booster Filter, is a dual-narrowband (hydrogen-alpha, oxygen-III) filter designed specifically for use in fast optical systems (systems with steep light cones/high angles of incidence). In testing this filter I found it was exactly what I needed to produce sharp, detailed images using my Celestron RASA 8 at f/2. In my one-shot color camera (OSC) I’m getting tremendous results with the IDAS NBX. The bandpass of both the hydrogen-alpha and doubly ionized oxygen (O-III) lines are both 10nm FWHM. This bandpass is narrow enough to block much of undesired light pollution, but wide enough to still allow ample light to be transmitted through the filter. As I mentioned this filter was designed for fast-optical systems. In fast systems, the light transmitted through a filter appears to be blue-shifted, or in other words, the light passed through the filter is of a shorter wavelength then intended. IDAS solves this problem for fast systems by pre-shifting the filter. That way when you use it, the light is blue-shifted into the desired wavelength, and you see that wavelength transmitted at a high percentage. In simulations with the filter IDAS shows a 90% transmission of the hydrogen-alpha wavelength, and a 95% transmission of the oxygen-III wavelength at f/2. Wow! That is VERY good! Overall, I’ve been extremely impressed with this filter, and it will be my dual-band filter of choice going forward for “high-speed” imaging.
