Astronomik MC Filter

This filter is designed for astro-imaging setups where you have modified your camera by removing the internal filter. It restores the original optical path length, ensuring your camera remains parfocal so you can achieve sharp focus without needing to adjust your lens or telescope setup.

No, it is a completely clear glass filter. Its purpose is to protect the sensor and maintain the correct focal plane without altering the spectral characteristics of the light reaching your sensor.

Yes, it acts as a protective barrier for your sensor, shielding it from dust, debris, and humidity. It is a critical addition if you have removed your camera's stock filter, which would otherwise leave the sensor exposed.

No, this specific model (SKU: ASF-C-EOS-1000D) is designed for specific Canon DSLR models. Please verify your camera model against the compatibility list before purchasing to ensure a proper fit.

The filter features a multi-coated surface that is specifically engineered to be scratch-resistant and water-repellent. It is built to withstand the rigors of long-exposure imaging sessions while maintaining high optical performance over time.

Being diffraction limited means the filter is manufactured to such high precision that it does not introduce any optical aberrations or distortions. It ensures that the glass itself is not the limiting factor in the sharpness of your images.
