HOYA PRO ND100000 67mm Filter
This filter is a neutral density filter designed for very long exposures, solar photography, and solar eclipses. A "filter factor" of 100,000 allows only 1/100,000 of the light that enters the filter to pass. Light reduction is just over 16.5 stops, necessary for the sun’s intensity during a solar eclipse. For lenses with a 67mm diameter. Use a step-up ring for lenses with smaller diameters and thread sizes.
