The instrument can be configured as a Lucernal microscope by adding a large additional body tube. The support rod bolts to the main tripod leg.
The Lucernal microscope can be used either with a large eyepiece or ground glass surface.
The two modes of Lucernal imaging are configured by removing one eyepiece lens (B) and inserting the ground-glass (C). Is this arrangement the eye lenses (A) are not used.
