The filters' refined transmission curves minimize unwanted light and optimize emission lines for more detailed imaging.

Engineered for Compatibility

The Astronomik Deep-Sky RGB Filterset 31mm is compatible with filter wheels from major brands like ZWO, QHY, Atik, and more. This set is designed to work seamlessly with a variety of sensors, including KAF, KAI, and Sony chips, allowing for balanced 1:1:1 RGB exposures with minimal post-processing.

Built to Last

The Astronomik Deep-Sky RGB Filterset 31mm is constructed with optically polished glass and durable, scratch-resistant coatings. These filters are made to withstand regular use, maintaining performance over time while delivering high-quality images.

Ideal for Light-Polluted Skies

For observers in light-polluted areas, Astronomik recommends using the CLS-CCD filter in place of a standard Luminance filter. This simple adjustment allows you to block unwanted artificial light and capture deeper, clearer images. Many users report significantly improved image quality after making this change.

Elevate your astrophotography with the Astronomik Deep-Sky RGB Filterset 31mm and experience the sharpness, contrast, and color fidelity these premium filters deliver.
