Narrowband Filters

The Askar ColorMagic Duo-Band filter is a dual or triple bandpass narrowband filter designed for light polluted skies for COLOUR CAMERAS to maximise the output from your imaging time.

Narrowband filters are used to create high contrast deep sky images of certain objects, mainly emission and diffuse nebulae (i.e. Veil Nebula, M42 Orion Nebula, North America Nebula, Horsehead Nebula) or planetary nebulae (i.e. M27 Dumbbell nebula, M57 Ring Nebula, Helix Nebula), just to mention few of well known nebulosities.

The ZWO OIII 7nm narrowband filter is designed for nebula observation allowing 7nm bandwidth of light centered on a wavelength of 500nm, which corresponds to OIII emission lines, blocking out all other light.

The ZWO SII 7nm narrowband filter passes light at 672nm wavelength with a bandpass of 7nm which is designed for nebula observation and imaging. It is suitable for visual observation on most emission nebulae, planetary nebulae and supernova remnants

L-eNhance provides an economical and practical solution for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras.

The ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras and offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.

Our novel MaxFR emission line filters are suitable up to very fast focal ratios. The new Astronomik MaxFR series of narrowband-emissionline filters are perfectly matched to the requirements of astronomical deep-sky imaging with fast optical systems.

L-Quad Enhance Filter is a quad bandpass light pollution suppression filter for colour cameras. It effectively
suppresses the transmission of light pollution wavelengths

This Astronomik OIII-CCD Filter is suitable for imaging of OIII nebulas from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 501nm and the background is increased enormous!

This SII-CCD Filter is suitable for imaging of SII-regions from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 672nm and the background is increased massively!

This H-alpha Filter is suitable for imaging of Hydrogen nebulas from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 656nm and the background is massively increased.
