    Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon

    The new fixed-post grinding machine is working on the 14.75 quartz mirror. This video shows rough grinding on the blank, which is done to get the mirror to the exact focal length we want. This mirror will have a focal length of 60 , which is F4. A steel-nut and die stone tool is fixed in place with a slight overhang over the edge of the mirror
