We will start with a short history of the art of mirror making and the role our own state of Vermont played in that timeline. This is followed by a description of the ten basic steps a mirror maker will take to transform a raw disk of glass into an optically perfect mirror that will reside the heart of their telescope. For each step\, we will describe the procedure to get to the desired result and a set of simple tests that prove that you have completed that task. In the end\, you will know how thousands of folks have crafted their own telescopes using the most basic tools to produce research quality optics. \nFollowing the main presentation\, our recurring monthly presentations will include Constellation of the Month  by Terri Zittritsch.
