IDAS NBZ-II Dualband Highspeed Narrowband Nebula Fliter O-III, H-Alpha - EOS drop-in holder

Name: IDAS NBZ-II Dualband Highspeed Narrowband Nebula Fliter O-III, H-Alpha - EOS drop-in holder
Brand: IDAS Filter
SKU: NBZ-II-DRE
Price: 419 EUR

The NBZ-II from IDAS is a dual-band nebula filter with O-III and H-alpha transmission - thanks to an improved arrangement of the transmission curves, the filter works with lenses and telescopes with f/1.9 and slower.

suitable for Meike MK-EFTR-C/MK-EFTE-C, Canon EF-EOS R drop-in mount adapter

Suitable for monochrome and color cameras

Can be used with all telescopes with f/1.9 and slower

The filter is very well suited for images of diffuse and planetary nebulae.

10 nm transmission in H-alpha, 8 nm in O-III

The artificial brightening of the sky (scattered light) is practically completely blocked.

High-quality anti-reflection coating - no halo problem around bright stars.

Scratch-resistant hard coating

2.0 mm thickness

Infrared light is blocked

Individually measured after production, measurement protocol is supplied

IDAS filters are produced in Japan

IDAS NBZ-II-DRE dual band nebula filter for fast telescopes and lenses

The NBZ filter is a dual line pass filter especially for EOS cameras. It is the successor to the NBZ/NBZex filter and is suitable for all telescopes and camera lenses from f/1.9 and slower.

The NBZ filter passes the red H-alpha line and the blue-green [O III] lines and increases the contrast. You obtain narrow-band images with only one exposure series.

The special feature of the NBZ-II nebula filter is that it is also suitable for very fast optics up to a focal ratio of 1:1.9, even with obstructed systems. This means that you can use the nebula filter on practically all common telescopes and most camera lenses.

The bandwidth of 10 nm for H-alpha and 8 nm for [O III] is slightly wider with the NBZ-II than with comparable 7 nm dual-band filters from other manufacturers. This somewhat wider bandwidth has the advantage that the filter can also be used on fast optics with similar contrast without a significant loss of transmission. This means that you do not have to buy a special narrow band filter for fast systems, as the NBZ-II can be used universally. In contrast, some of the competing filters with 7 nm or narrower bandwidth reduce transmission by 50 % or more when used in a fast optical system (around f/2).
