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.
