Lumicon markets its 0.15nm bandpass system as a Solar Prominence Filter, but it can show filaments at times. It requires a telescope that will be at least f/20 with the ERF applied. One side of the disk-shaped filter has a tube that slides into a 2" focuser. The other side has an adapter for 11⁄4" eyepieces. The unit has a screw that turns a tilting mechanism to tune the filter to the Hα line.

I saw no hint of the chromospheric network through the Lumicon filter. However, I could see large filaments faintly against the solar disk. Prominences were best through this filter, appearing as bright red features projected against a reddish-brown background. Although contrast between prominences and the sky was less than through the other filters, prominences looked best through the Lumicon filter.
