Telescope Mirror Making Kits - We provide complete kits for grinding and polishing high quality telescope mirrors.


TelescopeMirrorKits.com provides telescope makers with the most complete telescope mirror making kits available anywhere on the web. When you buy your telescope mirror kit from us, you get TWO glass telescope mirror blanks - one mirror blank is for your telescope mirror, the other glass blank is for your grinding tool - or you can use your second glass blank to make a second mirror if you choose. Both mirror blanks are 3/4" thick and TESTED for internal stress. You also get all mirror grinding abrasives, TWO types of mirror polishing compounds, and your choice of polishing pitch. We are telescope makers ourselves, and go the extra mile to provide you the most complete telescope mirror grinding kits available anywhere, at absurdly affordable prices. We've made ordering easy with one-click payment buttons below, so go ahead - order a telescope mirror kit today.

Why plate glass?


Because as Sky and Telescope says, there is NO DIFFERENCE in optical quality between plate glass and pyrex, and plate glass is far more affordable for you - that's why. Read Sky and Telescope's article regarding Pyrex vs. Plate here

Telescope Mirror Grinding Kits - Specifics:



All our mirror kits include two 3/4 inch mirror blanks, silicon carbide and aluminum oxide mirror grinding abrasives, your choice of Gugolz polishing pitch or Acculap synthetic pitch, and two separate polishing compounds - cerium oxide to get your mirror polished fast, and to finish, slow-acting red rouge - the time-tested favorite used by the best mirror makers throughout history. This second slow acting polishing compound allows you to "creep up" on that perfect figure, while providing the smoothest final optical surface attainable.
