Yes, it looks familiar. It's a development of a common planisphere with, perhaps, some application to navigation. But it doesn't much resemble the awful Rude star finder (also known as the HO 2102-D star finder) --except to the extent that the Rude star finder was also a development of a common planisphere. Would anyone care to make a list of all the features that make this Japanese star finder (assuming that's what it is) superior to the Rude star finder, so beloved by USN-worshipping navigation enthusiasts? Does it share any features with the Rude star finder that are not found on a common planisphere?
PS: There was a larger, somewhat more legible version of the image of this planisphere behind the one on the si web site:
