Hi friends, I am glad to faind a groop dedicated to the vacuum
technology.
I live in Argentina, and my english is not very good, I hope you
scuse my errors.
My main activity is the rebuilding of catode ray tubes (television
screens)but my hoby is atronomy.
I have the idea of using the front of obsolete cathode ray tubes, as
parabolic mirrow for telescopes.
This front is made of good cuality glass.
How you like the idea?
I am waiting for answers.
Albert Gasparini
