With this “filter” you can close an opening in filter wheels light-tight. This allows you to create dark images with cameras without their own shutter and to realize a “park” position of a filter wheel.
The Astronomik Dark-Filters fit perfectly in all filter wheels of the brands ZWO, QHY, QSI, Starlight Xpress, SBIG, Moravian and Atik.
