Description
MRF-coating: The advanced MRF coating technology ensures excellent performance, allowing the filter to be used on devices with apertures up to f/4. This coating enhances durability and light transmission, making it an ideal choice for astrophotography.
 
Alternative: Line filters with a 12nm full width at half maximum are particularly suited for DSLRs or CCD cameras with higher dark current. They are also the best option for cameras with built-in guiding chips, as they typically display twice as many stars in the image compared to narrower filters.
