That's fascinating. I'm the author of the piece, and the material trick and its ramifications is new to me, thank you! This entire subject is not my area of expertise - I'm an historian of 17th century astronomy - but it's been fun dipping my toes into this world.

Personally I find it a fascinating hobby and never run out of fun things to research/build/test.
