The IR Pro (742nm) Filter pushes the passband of the Baader and Altair IR pass filters further into the Infra Red. At these longer wavelengths, planetary images are much less disturbed by distortions in the atmosphere.
This is the best “Planet Killer” filter, based on research by Astronomik to determine the optimal passband for enhanced Planetary Imaging, with most amateur equipment.
Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit.
Astronomik MC-Clear Canon EOS 1000D, 100D, 450D – 760D, 40D – 70D, 7D For Full Spectrum Modification.
Special glass for retrofitting Canon® EOS DSLR cameras to achieve the full spectral sensitivity of the CMOS sensor. Price includes UK delivery.
The Astronomik H-alpha 12nm CCD Clip Filter EOS XL is a narrow band filter for CCD photography. This filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.
Astronomik offers an additional series of high-end RGB filters: The new Astronomik Deep-Sky RGB filter set is specially designed to meet the needs of modern astrophotographers for maximum image quality with all CCD cameras.
Use the Deep-Sky RGB Filter Set to capture images with unparalleled sharpness, contrast, and vivid color.
This Astronomik SII CCD Filter 6nm is suitable for photographing SII regions from artificially polluted areas as well as places with dark skies. The contrasts between objects that glow in the light of the sulfur line at 672nm and the sky background are greatly enhanced.
The 6nm SII-CCD filter dramatically increases the contrast between hydrogen fog and the sky background.
The Astronomik OIII CCD Filter 6nm dramatically increases the contrast between hydrogen fog and the sky background.
Due to the combination of low half-width and high transmission of almost 100% in the area of the OIII line, the filter delivers a maximum signal in the desired wavelength, but blocks all other radiation and thus ensures an extremely dark sky background.
This Astronomik UHC-E Filter was designed for visual observation of emission and planetary nebulae with smaller telescopes (<8″) but also works well for imaging these objects if used with an IR block filter.
