IDAS NBZ Nebula Booster Filter, 45mm dia., unmounted dual bandpass, H-α and OIII
- 10nm bandpass for Ha and OIII respectively.
- IDAS-proprietary “flat-top”, “steep cut-off” and “off-center” design eliminates the emissions’ signal loss due to the spectrum shift until F2 speed.
- No IR blocker required
IDAS NBX Filters are designed to enhance the contrast of Hα and OIII emission nebula, yet accommodate 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
