Hoya Pro ND100000 77mm Solar Eclipse Filter

The Hoya PRO ND100000 filter is a 16 3/5 stop neutral density filter designed for multiple photographic applications including very long exposures, solar photography, and solar eclipses. This is a ultra-dark filter with a "filter factor" of 100,000 meaning it only passes 1/100,000 of the light that enters the filter. That translates to a light reduction of just over 16.5 stops. This is necessary due to the sun’s intensity even during a solar eclipse. The more than 16.5 stops of light reduction can also yield exposure times of several minutes during daytime where the sun is not actually in the photo. Hoya uses a precise metal vapor deposition process to create the ultra-dark ND effect while maintaining a very neutral color balance for faithful color reproduction at very long exposure times. The PRO ND100000 is available in 4 common filter sizes. If the size is not available to match a particular lens, purchase the next larger size and use an appropriate step-up ring. Step rings are available on our sister website at Kenko USA. Click here to open a new window to that website.

Caution, Please Read:
The Hoya PRO ND100000 is not suitable eye protection for viewing of sun or solar eclipses. Do not look directly or indirectly into the sun without appropriate eye protection. The ND100000 should be installed in front of the camera lens or telescope before the trying to align it with the sun. Do not use an optical viewfinder when aligning your camera or telescope with the sun. If the camera has a LCD screen with a live-view feature, use that to align it with the sun and for viewing.
