     I think you would be much happier with a solid aluminum baffle. Strong,
firm, fireproof (a consideration when viewing planets near the sun).

     Precisely.
     Here is a link to a fireproof Cass. Page down to the photos of the
baffles. They are integral with the cells. Simple, accurate, secure.

     Make your Cass well and it will treat you well.   ;)
