Astronomik Deep-Sky Filter

This set is specifically optimized for deep-sky imaging, such as capturing galaxies and nebulae. It is designed to isolate and enhance the specific wavelengths of light needed to produce vibrant, high-contrast RGB color data.

These are 31mm round mounted filters. Before purchasing, ensure your filter wheel or filter drawer system is compatible with 31mm mounted optics to avoid vignetting or fitment issues.

Using these filters helps block unwanted light pollution and atmospheric noise while allowing the specific light from deep-sky objects to pass through. This results in cleaner, more detailed images with significantly better color separation.

Yes, this is a three-piece set designed to capture the necessary RGB color channels. By combining the data from these three filters, you can create a full-color composite image of your target.

These filters are crafted from high-quality optical glass. This material ensures excellent light transmission and minimal distortion, which is critical for maintaining sharpness during long-exposure deep-sky photography.
