Ronchi eyepiece photographic 5L/mm
Many customers asked for it, now it is ready for sale: The photographic Ronchi!
Since I first offered my Ronchi eyepiece a couple of years ago, many customers asked for a way to take images of the Ronchigramms. This is possible with the new version now!
The photographic Ronchi has the same high-quality grating inside, which is made of evaporated chrome on polished glass (127 lines per inch or 5 lines per millimeter). Contrary to the visual version, it has no 1,25" barrel but a T-thread on one side and an M52 thread on the other. With the T-thread, you may mount the photgraphic Ronchi on nearly all instruments. (Matching adapters are already owned by most amateurs.) On the other side of the Ronchi, you may install your camera (WITH A NORMAL LENS INSTALLED!!) at the M52 thread. (You might need a matching Step-Ring for your lens.)
The surface of the grating is in the same plane as a outer rim, so the focal plane of any instrument can be found very easy!
The new photographic Ronchi may be used visually too, without any restrictions.
