I have been looking through websites with the intent to build a telescope. I have been looking at mirrors today and there are many to choose from including prefabricated ones which I will use for my first scope.
But my question is with regards to the the other non prefabricated glass...
Is it necessary to use glass that needs to be polished down? Why not curve some other material like aluminum and then coat it with some reflective plating?
It seems time and cost effective to do it the latter way, but I am sure there is some reason why it is not used
Someone please enlighten me,
Casey
