    Re: Neat video about LEM stellar alignment scope

    I liked that video!  Nicely explained and the graphics were simple to follow. 

    The Archimedean Spiral was a neat trick.  A trick that I was unaware that they used.  So I learned something today! 

    Thanks Paul!

    This is a nice video about the Apollo LEM alignment telescope that was designed with some clever work-arounds as a lightweight substitute for a more conventional sextant: https://www.youtube.com/watch?v=hVCNS2jQQ6g    -p
