Not sure how good the book is but might at least give some ideas although it’s not a how to book.There os another book by the same author but it covers the building of a 10” newt binoscope not a refractor binoscope.

Tracking is showing as “Order data transmitted electronically.” but no tracking info yet.

I think these are Helicoids, a system invented by Tatsuro Matsumoto.  Two flat mirrors are arranged at precise angles to produce a 90 degree viewing angle with terrestrial orientation.     🙂
