Gerd Neumann's Ronchi Eyepiece employs a chrome-on-glass grating of 10 lines per millimetre, providing a high-contrast display of starlight that enables good analysis of the optical train.

Colored filters can be used to bring out details on a planet’s surface or its cloud structure.

You can now use this filter to focus perfectly with a bright image and since they are also parfocal, switch to a different narrow band filter without loosing the focus.
