ZWO 2" Duo-Band Narrow Band Nebula Filter for Color and Astro Cameras

Name: ZWO 2" Duo-Band Narrow Band Nebula Filter for Color and Astro Cameras
Brand: ASI - ZWO
SKU: ASIDB2
Price: 239 EUR

The ZWO DB2 Duo-Band dual-bandpass filter allows nebula photography with colour cameras and monochrome cameras and significantly reduces light pollution.

The filter enables images close to the quality of monochrome cameras with narrow-band filters.

The filter is ideal for extremely high-contrast luminance images with monochrome cameras.

H-alpha and O-III are allowed to pass almost unhindered

The striking nebula colour (RGB) is best preserved for a natural impression.

2" low-profile filter mount

The filter is compatible with all filter holders, filter drawers and filter wheels.

Manufacturer: ASI - ZWO

ZWO Duo-Band Narrow-band Filter for high-contrast Nebula Images even close to Cities

The ZWO Duo-Band narrow band filter is an alternative to time-consuming astrophotography with L-RGB filters and monochrome cameras. With this filter, high-contrast nebula images can also be captured with color astro cameras and DSLR cameras.

The ZWO Duo-Band Filter is a dual-band pass filter that was specially developed for color cameras. The important areas in which nebulae glow, such as H-alpha, H-beta and oxygen (O-III), are let through almost unhindered. The rest will be blocked. The natural colour of the nebula is preserved in the best possible way. The results are astrophotographic results reminiscent of missions in the dark high mountains.

The filter is also suitable for monochrome (black and white) cameras. The contrast of the luminance images is extremely increased, even very faint nebulae can be recorded well.
