Kase K100 Night Kit (Neutral Night Filter + Focus Tool)

The K100 Night Kit from Kase features the Kase K100 Wolverine Neutral Night Filter (anti-light pollution) and the K100 Precision Focus Tool. Both are compatible with the K9 filter holder.

The night filter, designed with glass optics, reduces the effect of artificial light for night shots. The focus tool lets you achieve sharp manual focusing on light sources at night. You can use it on stars or artificial light sources. A series of thin lines are etched into the glass surface, allowing you to focus on a light spot. To use the focus tool, just place it in the filter holder, focus manually, and then remove it and swap in the night filter to get rid of unwanted light pollution.
