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.
