This H-alpha Filter is suitable for imaging of Hydrogen nebulas from observation sites with light pollution and from dark sites as well. The FWHM of 6nm is matched to give you optimal performance with CCD and CMOS sensors with a very low dark current!
The Astronomik H-beta filter is a narrow band emission-line filter for CCD photography. The filter lets the H-beta light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.
The 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!
The Astronomik SII-CCD filter is a narrow-band-filter for CCD photography.The filter lets the light of the ionized sulfur (SII) pass, and blocks nearly the whole remainder of the visual spectrum as well as IR, in which the CCD is sensitive.
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.
L-Quad Enhance Filter is a quad bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths
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.
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
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.
