Gerd Neumann Jr. Photographic 10LP/MM Eyepiece
The Gerd Neumann Jr. Photographic Ronchi Eyepiece has the same high-quality grating inside, which is made of evaporated chrome on polished glass (254 Lines per” or 10 Lines per millimeter). Contrary to the visual version it has no 1.25″ barrel but a T-thread on one side and M52 on the other. With the T-thread you may mount the Photographic Ronchi on nearly all instruments.On the other side of the Ronchi you may install your camera on the M2 thread (You might need a matching Step-Ring for your lens).
The surface of the grating is in the same plane as an outer rim, so the focal plane of any instrument can be found very easy! The new Photographic Ronchi may be used visually without any restrictions.
