The IDAS NBZex is a dual band nebular booster filter that transfers OIII and H-alpha emission lines with the band width of 12nm (+/-0.4nm) at each band. Halos that occurred around the ojbects with the predecesor "NBX" filter can now be decreased 1/100th thanks to the technology we have developed to surpress the repetitive reflections of the ...

2021年1月27日 · The IDAS NBX filter is a similar filter, but with wider bandpass at about 15nm compared to the L-eXtreme's 7nm. That added width, plus their design which places them off center a bit to allow for more bandpass shift at fast f/ratios, means they are touted as working with scopes as fast as f/2.

2021年5月6日 · The IDAS NBX Nebula Filter is a dual band filter that excels with nebula photography using fast optics, like the Celestron RASA. The NBX is a dual filter which specifically focuses on OIII and H-alpha lines and, like the existing IDAS (Astro Hutech) nebula filters, the new NBX is of impeccable quality and workmanship.

A new generation filter covering multiple objects including comets, galaxies, the Milky Way, and emission and reflection nebulae, by making use of the extra tranmission in the NIR region.

The NBZ is a dual band nebular booster filter that transfers OIII and H-alpha emission lines with the band width of 12nm (+/-0.4nm) at each band. Halos that occurred around the ojbects with the predecesor "NB X" filter can now be decreased 1/100th thanks to the technology we have developed to surpress the repetitive reflections of the filter ...

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.

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.

Optical Distance Worker ODW clear filter (used instead of NB2-PM/NB3-PM) to correct the optical distance. The NB2 is a nebula booster filter that transfers OIII, H-alpha and NII emission lines, and the NB3, OIII and SII emission lines respectively.

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.

2021年11月9日 · program so that NBX users don’t have to pay for a new filter to get the improved performance. The NBZ-UHS is the newest filter, which is further optimized for optics faster than f/2.8....
