The Astronomik UHC-E filter is tailored for deep-sky observation of emission nebulae and comets under light-polluted skies, especially ideal for smaller telescopes up to 5" (125mm) aperture. It enhances the contrast between these celestial objects and the sky background by blocking typical streetlight emissions, as well as all lines of natural airglow.
With a Full-Width-Half Maximum (FWHM) of 45nm, the Astronomik UHC-E filter ensures a significant contrast boost while allowing a greater amount of starlight to pass through compared to its counterpart, the Astronomik UHC filter. This characteristic makes it particularly well-suited for smaller telescopes, enhancing visibility without compromising on the overall brightness. Additionally, its transmission range includes spectral lines, enhancing the observation of comets.
In essence, the Astronomik UHC-E filter is a versatile tool for enhancing contrast under urban sky conditions, especially for observers using smaller telescopes to explore the depths of deep-sky objects and comets.
AlternativesÂ
- For telescopes larger than 5" (125mm), we recommend upgrading to the standard Astronomik UHC filter, which provides even greater contrast enhancement capabilities.
- For telescopes exceeding 8" (200mm), we suggest an Astronomik OIII visual filter as first filter.
Suitability of the Astronomik UHC-E filters
- Visual observation (dark skies): Reasonable, an Astronomik UHC filter is more suitable
- Visual observation (urban skies): Good, for telescopes up to 5" (125mm) aperture
Clip-Filters for mirrorless Canon EOS M cameras
Since 2007 we offer our extremely popular Astronomik Clip-Filters. The complete range of Astronomik filters is available as Clip-Filters for the compact mirrorless Canon EOS M series.
The Astronomik Clip-Filters offer a number of practical advantages that make them an ideal choice for astrophotographers:
- Installing and removing the Astronomik Clip-Filter is very quick and easy and requires no extra tools or modifications to the camera body. They can be changed at any time, even at night.
- All lens functions, such as focus, aperture, and image stabilization remain fully functional.
- The Astronomik Clip-Filters are held securely in place without stressing the high-quality glass.
- The Astronomik Clip-Filters are designed and optimized for use with both standard camera lenses and telescopes.
Through the Astronomik Clip-Filters, we were able to solve several common issues faced by astrophotographers:
- Large filters for large camera lenses are very expensive.
- Using a filter holder between the camera body and the lens prevents focusing to infinity.
- For very fast telescopes (low f-number) like the Vixen R200SS or the Takahashi "Epsilon" astrograph, a filter drawer or filter wheel can not be used because the distance to the corrector lenses would be changed.
- Long exposure times lead to dust settling on the camera's sensor chip.
Additionally, all Astronomik EOS M Clip-Filters serve as an excellent dust shield, protecting the sensor during long exposures. If you only need a dust shield without filtering effects, the Astronomik MC-Clear EOS M Clip-Filter is the right choice.
Use Astronomik filters for your Canon EOS M camera and enjoy marvelous images with an ultra light equipment!

Astronomik XT-Filters
The 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.
Since many years, Astronomik Clip-Filters are a popular and well known tool among astrophotographers worldwide. However, 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 finely polished, free of any striae, residual stresses, and bubbles, and are suitable for the most advanced imaging applications.
The Astronomik XT-Filters are manufactured using the same durable coating technology as all Astronomik filters. They are extremely scratch-resistant, unaffected by high humidity, and do not degrade over time. This ensures they retain their performance for years. As with all our filters, we underline this promise with a 10-year warranty.
Please note that not all Astronomik filters are available as XT-versions due to the complexity of manufacturing these ultra-thin filters. Currently, filters are produced that are predestined for photography with wide-angle lenses.

- Typical transmission of 95% at 496nm (OIII)
- Typical transmission of 95% at 501nm (OIII)
- Typical transmission of 94% at 656nm (H-alpha)
- Transmission range: 465nm to 530nm and above 645nm
- Full-Width-Half Maximum (FWHM): 45nm
- Glass thickness: 1mm (except Astronomik OWB Type 3 and XT filters)
- Finely polished optical glass, free of any striae, residual stresses, and bubbles
- Extremely scratch-resistant and durable coating
- Completely resistant against high humidity and aging effects
- Parfocal with other Astronomik filters
- Diffraction-limited
- Optimized spectral windows
- Delivered in a high-quality, long-lasting filter box
Due 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.
