The Astro Duo-Narrowband filter is meticulously crafted to capture the distinct wavelengths emitted by gaseous and planetary nebulae. It prioritizes the Hα emission line at 656nm and OIII lines at 500nm, boasting high transmission while effectively combating light pollution and blocking longer wavelengths. This results in enhanced detail and contrast in your astrophotography.

The STC Astro Multispectra filter serves as a versatile light pollution suppression tool, tailored for DSLR cameras, effectively countering interference from artificial sources like mercury and sodium street lights. While minimizing unwanted light, it preserves crucial nebula emission lines, heightening the contrast of celestial objects. 

Introducing the STC Astro-Multispectra filter, a versatile solution engineered to combat light pollution and optimize astronomical photography with Nikon DSLRs. This filter effectively mitigates the disruptive effects of artificial lighting, such as those from mercury and sodium street lamps, while preserving crucial nebula emission lines.

The STC Filters Astro Nightscape Clip Filter for Sony cameras is a specialized broadband filter designed to reduce light pollution and enhance nightscape photography. This filter is installed directly above the camera sensor, making it easy to use with compatible Sony models. Its advanced coating technology helps preserve natural colors while minimizing unwanted color shifts and maintaining sharp focus across the image.

The STC Filters Duo-NB Clip-Filter for Sony (APS-C) is a narrowband filter designed to boost contrast in astrophotography by allowing only certain wavelengths of light to pass through. It is especially effective for capturing specific spectral lines such as hydrogen-alpha (H-a at 656 nm), oxygen (OIII at 501 nm), and sulphur (SII at 672 nm). This filter is suitable for use even in light-polluted environments or when the Moon is present, making it ideal for city-based or lunar-phase astrophotography.

The STC Filters Duo-NB Filter for Canon EOS R is a narrowband filter designed to enhance contrast in astrophotography by allowing only specific wavelengths of light to pass through. It targets important spectral lines such as hydrogen-alpha (H-a at 656 nm), oxygen (OIII at 501 nm), and sulphur (SII at 672 nm), making it ideal for capturing nebulae and other deep-sky objects. This filter is effective even in light-polluted environments or when the Moon is visible, allowing for both short and long-exposure photography without significant loss of detail.

The STC Filters Duo-NB Clip for Canon Full Frame cameras is a narrowband line filter designed to increase contrast in astrophotography. It works by allowing only specific wavelengths of light to pass through, such as those corresponding to hydrogen-alpha (H-a at 656 nm), oxygen (OIII at 501 nm), and sulphur (SII at 672 nm). This filter is effective for capturing detailed images of nebulae and other deep-sky objects, even in light-polluted areas or when the Moon is present.

The STC Infrared Clip-Filter 590nm for Sony cameras is designed to block visible light and allow only infrared wavelengths to pass through. This makes it suitable exclusively for photographic applications, as infrared light is invisible to the human eye. IR Pass filters are commonly used in astrophotography at high magnification because atmospheric turbulence is reduced in the infrared spectrum, allowing for sharper and more detailed images.

The STC Infrared Clip-Filter 720nm for Sony cameras is designed to block all visible light and allow only infrared wavelengths above 720 nm to pass through. This filter is intended solely for photographic use, as infrared light is invisible to the human eye. IR Pass filters are especially valuable in astrophotography at high magnification, since atmospheric turbulence is less pronounced in the infrared spectrum, allowing for the capture of finer details-such as sharp images of Mars or the Moon.

The STC Infrared Clip-Filter 850nm for Sony cameras is designed to block all visible light and allow only infrared wavelengths above 850 nm to pass through. This filter is intended exclusively for photographic applications, as infrared light is invisible to the human eye. IR Pass filters are especially useful in astrophotography at high magnification, where atmospheric turbulence is reduced in the infrared spectrum, enabling the capture of finer details-such as sharp images of Mars or the Moon.

The STC Filters Astro Nightscape Clip-Filter for Nikon APS-C cameras is a broadband filter designed to improve nightscape and astrophotography images by reducing the impact of light pollution. This filter is particularly effective for capturing nebulae, galaxies, and hydrogen nebulae, allowing for clearer and more vibrant photographs even in areas with significant artificial lighting. It is intended for photographic use only and is not suitable for visual observation.

The STC Filters Duo-NB Clip-Filter for Nikon (APS-C) cameras is a narrowband filter designed to enhance contrast in astrophotography by allowing only specific wavelengths of light to pass through. It targets important spectral lines such as hydrogen-alpha (H-a at 656 nm), oxygen (OIII at 501 nm), and sulphur (SII at 672 nm), making it ideal for capturing nebulae and other deep-sky objects. This filter is effective even in light-polluted environments or when the Moon is present, and can be used for both short and long-exposure photography.
