Imaging Filters

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.

The IDAS HEUIB-II (H-α Enhanced UV IR Blocking) filter is designed for enhanced spectrum DSLR's and one-shot color CCD astronomical cameras.

The P2 is the most popular filter for suppressing light pollution with modern CCD, CMOS and DSLR cameras. Japanese made for the highest possible quality.

The LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components red, green, blue and luminance.

The Optolong extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light

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 Optolong L-Pro (L-Professional) filter is designed to provide maximum luminosity of the spectrum other than those areas caused by light pollution

The Antlia Triband RGB Ultra filter is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands.

IDAS NB Filters are designed to enhance the contrast of emission nebula, yet accommodate the filter spectral shift* when used with modern fast optical systems.

The Antlia H-alpha EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4.5nm bandpass. The suppression of optical density (OD 5) on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro.

Antlia OIII 4.5nm EDGE filters are designed to deliver 85% transmission at the 500.7nm line that provides you with the maximum signal to reveal the faintest OIII nebulae structures.

High transmittance for working with both long focal ratios and fast optical systems (as fast as f/3 or maybe even f/2.8)!

This premium grade ultra narrowband 4.5nm Baader Sulphur II (S-II) filter is for use with fast optical systems with focal ratios between f/3 to f/8.

This narrowband filter has a 7nm bandwidth of light centered on a wavelength of 656nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light

OIII-CCD 7nm filter is designed for nebula observation allowing 7nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light

Extra narrowband SIICCD 7nm filter (Sulful II for CCD) is designed for nebula observation allowing 7nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light
