I'm adding some notebook scans from 07 July (wrongly labelled as June), with initial ideas about the first reticule's composition.

I'm trying the configurations for more reticules. There is another brass based block with alternating square and circular fields of dots; I can find a rather irregular positioning of the slides, at least if I include the circular fields. And there one of the two smaller wooden-only blocks I found in Graz, which allows a very calm singular direction positioning. The two less sophisticated blocks I got on ebay with a cheaper looking bright wood and thinner metal teeth cannot really hold the glass slides as such. I like them as a duo, but I'm not sure now how and if I'm going to use them.
The ‘starfield’ reticule and the ‘rows’ reticule could work as single nodes with six channels.
