Astronomik UHC filter
The Astronomik UHC filter stands out as the first choice for astrophotography of emission nebulae, offering enhanced contrast and detail that surpasses other filters on the market.
With its Ultra High Contrast (UHC) design, the Astronomik UHC filter allows nearly 100% transmission of H-alpha, OIII and H-beta lines, effectively eliminating scattered light from various sources, including light pollution. This results in a significant enhancement of detail for gaseous and planetary nebulae against the sky background.
Designed for versatility, the Astronomik UHC filter is effective in both urban and dark sky conditions, improving contrast for emission nebulae. It dramatically increases the visibility and detail of objects that are otherwise faint or obscured.
The filter’s application spans aperture ratios from 1:3 to 1:15, suitable for a wide range of telescopes and lenses. Compared to filters from other manufacturers, the Astronomik UHC filter excels in revealing more stars and finer details in celestial objects, maintaining the sharpness and optical quality expected from high-performance lenses.
The filter works by blocking the whole optical spectrum, but allowing H-alpha, OIII and H-beta lines to pass through. This highly selective transmission enhances the contrast between the sky background and objects.
In summary, the Astronomik UHC filter is indispensable for astronomers seeking to maximize visual clarity and contrast when photographing emission nebulae, making it an essential tool for all deep-sky photographers alike.
Other uses
The 1.25"- and 2"-cell models can be used for visual observations as well.

Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Thanks to the high-precision machining of the glas substrate, all Astronomik filters are parfocal. The wedge errors are far below all common tolerances. Therefore, all issues concerning focal distances and the exact alignment of images from each color channel are effectively eliminated.
All Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR and MaxFR coatings are designed for optimal performance across a wide range of focal ratios of the optics used.
Every Astronomik filter undergoes a rigorous quality control process before delivery. Additionally, each Astronomik Narrowband-Emissionline filter is measured using a high-end PerkinElmer Spectrophotometer to ensure it meets the specifications published on our website. On the back of each Narrowband-Emissionline filter box, you will find a label detailing the precise spectral data for that specific filter, including the maximum transmission and the recommended range of focal ratios for best performance of that specific filter.

With its Ultra High Contrast (UHC) design, the filter allows nearly 100% transmission of OIII and H-beta lines, effectively eliminating scattered light from various sources, including light pollution. This results in a significant enhancement of detail for gaseous and planetary nebulae against the sky background.Designed for versatility, the Astronomik UHC filter is effective in both urban and dark sky conditions, improving contrast for emission nebulae and other celestial objects. It dramatically increases the visibility and detail of objects that are otherwise faint or obscured.The filter's application spans aperture ratios from 1:3 to 1:15, suitable for a wide range of telescopes and lenses. Compared to filters from other manufacturers, the Astronomik UHC filter excels in revealing more stars and finer details in celestial objects, maintaining the sharpness and optical quality expected from high-performance lenses.The filter works by blocking emission lines from high- and low-pressure sodium (Na)- and mercury (Hg)-vapor lamps and all lines of natural airglow, while allowing H-beta and OIII lines to pass through. This selective transmission enhances the contrast between the sky background and observed objects.Additionally, the Astronomik UHC filter is recommended for photography of Jupiter's clouds and offers improved separation of double stars. In summary, the Astronomik UHC filter is indispensable for astronomers seeking to maximize visual clarity and contrast in deep-sky photography, making it an essential tool for all deep-sky photographers alike.Other usesThe 1.25" and 2" socket models can be used for visual observation.AlternativesThe Astronomik UHC-E filter is more suitable for photographing comets or when there is less light pollution.We recommend the Astronomik CLS or CLS CCD filter for photographing galaxies and the milky way in moderate light pollution. The Astronomik CLS CCD filter has an additional integrated infrared(IR)-blocking layer.Suitability of the Astronomik UHC filtersCMOS and CCD photography: Good for emission nebulae, requires an additional Astronomik IR-Block filterDSLR photography (original): Good for emission nebulae, color balance is shifted but contrast is enhancedDSLR photography (astro-modified): Very good for emission nebulae, color balance is also goodDSLR photography (MC-modified): Very good for emission nebulae, requires an additional Astronomik IR-Block filterDifference between Astronomik standard and XT Clip-FiltersThe new Astronomik XT-Filters are specifically designed for astrophotography with wide-angle lenses, delivering sharp and crisp star images all the way to the edges of the image. When using very short focal length lenses to take widefield images, standard Clip-Filters could introduce aberrations, stretching stars in the outermost corners of the image. To solve this issue, the new Astronomik XT-Filters are coated on an extremely thin substrate of only 0.3mm or 0,5mm thickness, significantly reducing these aberrations. Despite the reduced thickness, the Astronomik XT-Filters maintain the highest optical quality. They are manufactured using the same durable coating technology as all Astronomik filters. More information about our XT-Filters can be found here.Technical dataTypical transmission of 95% at 486nm (H-beta)Typical transmission of 95% at 496nm and 501nm (OIII)Typical transmission of 95% at 656nm (H alpha)Transmission range: 480nm to 505nm and above 645nm Full-Width-Half Maximum (FWHM): 25nmGlass thickness: 1mm (except Astronomik OWB Type 3 and XT filters)Finely polished optical glass, free of any striae, residual stresses, and bubblesExtremely scratch-resistant and durable coatingCompletely resistant against high humidity and aging effectsAstronomik MFR coating (Astronomik Deep-Sky RGB, UV-IR Block L-1, L-2, L-3, and Narrowband-Emissionline filters)Parfocal with other Astronomik filtersDiffraction-limitedOptimized spectral windowsDelivered in a high-quality, long-lasting filter boxDue to the high-precision machining of the carrier substrate, all Astronomik filters are parfocal with wedge errors far below all common tolerances. Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Issues concerning focal distances and the exact alignment of images from each color channel are therefore effectively eliminated. All Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR coating is designed for optimal performance across a wide range of focal ratios of the optics used.Every Astronomik filter undergoes a rigorous quality control process before delivery. Additionally, each Astronomik Narrowband-Emissionline filter is measured using a high-end PerkinElmer Spectrophotometer to ensure it meets the specifications published on our website. On the back of each Narrowband-Emissionline filter box, you will find a label detailing the precise spectral data for that specific filter, including the maximum transmission and the recommended range of focal ratios.

The Astronomik CLS CCD filter has an additional integrated infrared(IR)-blocking layer.Suitability of the Astronomik UHC filtersCMOS and CCD photography: Good for emission nebulae, requires an additional Astronomik IR-Block filterDSLR photography (original): Good for emission nebulae, color balance is shifted but contrast is enhancedDSLR photography (astro-modified): Very good for emission nebulae, color balance is also goodDSLR photography (MC-modified): Very good for emission nebulae, requires an additional Astronomik IR-Block filterTechnical dataTypical transmission of 95% at 486nm (H-beta)Typical transmission of 95% at 496nm and 501nm (OIII)Typical transmission of 95% at 656nm (H alpha)Transmission range: 480nm to 505nm and above 645nm Full-Width-Half Maximum (FWHM): 25nmGlass thickness: 1mm (except Astronomik OWB Type 3 and XT filters)Finely polished optical glass, free of any striae, residual stresses, and bubblesExtremely scratch-resistant and durable coatingCompletely resistant against high humidity and aging effectsAstronomik MFR coating (Astronomik Deep-Sky RGB, UV-IR Block L-1, L-2, L-3, and Narrowband-Emissionline filters)Parfocal with other Astronomik filtersDiffraction-limitedOptimized spectral windowsDelivered in a high-quality, long-lasting filter boxDue to the high-precision machining of the carrier substrate, all Astronomik filters are parfocal with wedge errors far below all common tolerances. Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Issues concerning focal distances and the exact alignment of images from each color channel are therefore effectively eliminated. All Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR coating is designed for optimal performance across a wide range of focal ratios of the optics used.Every Astronomik filter undergoes a rigorous quality control process before delivery. Additionally, each Astronomik Narrowband-Emissionline filter is measured using a high-end PerkinElmer Spectrophotometer to ensure it meets the specifications published on our website. On the back of each Narrowband-Emissionline filter box, you will find a label detailing the precise spectral data for that specific filter, including the maximum transmission and the recommended range of focal ratios.
