Chroma Photometric Sloan DSS R Telescope Filter

The Sloan DSS 'R' filter is designed to isolate the red portion of the visible spectrum. It is a standard in photometric research, allowing you to capture consistent, scientifically accurate data that matches professional survey datasets.

The 31mm size is a standard dimension for many filter wheels used in astrophotography. Before purchasing, verify that your specific filter wheel or telescope interface is compatible with 31mm round, unmounted filters.

This is a photometric filter specifically engineered for imaging applications. While it will technically pass light, it is optimized for the precision required by digital sensors and scientific data collection rather than visual eyepiece viewing.

Like any high-quality optical glass, you should handle the filter by its edges to avoid oils from your skin. When cleaning becomes necessary, use only professional-grade optical cleaning solutions and microfiber cloths designed for delicate telescope optics.

A broadband filter allows a wider range of light wavelengths to pass through compared to narrowband filters. This makes it highly versatile for general-purpose imaging where you want to capture more signal from the target while still maintaining the specific spectral characteristics of the Sloan 'R' band.
