Notes:
The engravings of the Instantaneous Shutter of 1884 and the Eclipse Instantaneous Shutter of 1886 are not identical, but they are so close that the Eclipse Instantaneous can be thought of as a refinement of the Instantaneous. Photographing eclipses was a subject much in the news in the 1880's. Since the sun is rather bright, an instantaneous shutter would have been employed. Perhaps the change of the name commemorates just such a use by a scientific team 1884-1885.
