This allows imagers to use their filters without the added thickness and potential vignetting of a standard metal cell, which is critical in fast optical systems.

By connecting two or more bases in series, you can house multiple filter sliders simultaneously, creating combinations of narrowband, LRGB, or photometric filters that would otherwise require a large, heavy filter wheel.
