This video shows a few initial stages of making a primary mirror for a 6" f/8 telescope. I'm a newbie so bear with me in my ignorance as a first timer making a Telescope. I actually purchased (during the making of this video compilation) a granite flat plate ($12) to zero my custom built spherometer... The final part of the video shows the result of fine grinding with 5 micron abrasive. Sorry about the sniffles, I had a bad cold for about 2 weeks...
