Astronomik Deep-Sky RGB Filter Set 36mm, 3 filters

Our 36mm filters fit perfectly in all 36mm filter wheels from brands such as ZWO, QHY, QSI, Starlight Xpress, SBIG, Moravian, and Atik. Designed with a protective ring and blackened filter edges to prevent stray light, they are mechanically protected and easy to handle.

The orientation of the filter in the filter wheel does not affect the optical performance, making it easy to set up and use.

Astronomik Deep-Sky RGB Filters

Astronomik has introduced a new range of RGB filters designed for maximum deep sky imaging performance with CCD cameras. These filters enhance your imaging experience, delivering high-quality data for sharp, high-contrast, and vivid images.

Key Features of Astronomik Deep-Sky RGB Filters:

• Maximum transmission of up to 95%
• Ultra-sharp, pinpoint star images
• High contrast for clearer images
• Easy-to-process data for vibrant colours in final images
• Optimised spectral windows for maximum photon capture on the sensor
• Crafted with finely polished, high-quality optical glass
• Extremely durable, scratch-resistant coating
• MFR Coating technique for a wide range of focal ratios

The Result of Expert Research

The new Astronomik Deep-Sky RGB filters are the culmination of extensive research and development. These filters are designed to provide vivid colours and excellent contrast, making deep sky imaging easier and more rewarding.

These RGB filters are optimised for modern CCD camera sensors, allowing you to achieve stunning results with minimal post-processing. The transmission curves of the filters are engineered to eliminate halos and reflections, ensuring even bright stars appear sharp and clear.

Added Value for Light Polluted Areas:

If you observe in areas with light pollution, consider using the CLS-CCD filter as a replacement for the Luminance filter. This can help block unwanted artificial light while delivering balanced energy across the colour channels, enabling you to capture deeper and more detailed images.
