Baader Planetarium SLOAN/SDSS Photometric Filter

Yes. The filters are specifically designed to perform well with modern CMOS sensors while remaining fully compatible with traditional CCD cameras, ensuring consistent results regardless of your sensor technology.

Reflex-Blocker technology is an advanced coating process that significantly reduces internal reflections and halos. This is particularly useful when imaging bright stars or working in high-contrast environments, resulting in cleaner, more accurate photometric data.

These filters are optimized for a wide range of focal ratios, from f/15 down to f/1.8. This makes them versatile enough to handle everything from long-focal-length planetary setups to fast, wide-field astrographs without compromising image quality.

They are built for durability using ion-beam coating technology and sealed coating edges. This construction makes them highly resistant to moisture and temperature extremes, preventing the degradation often seen in standard filters over time.

The filters feature blackened edges specifically to eliminate stray light reflections. This design choice helps ensure that the light reaching your sensor is strictly the light passing through the filter, which is critical for precise photometric measurements.
