Telescope Mirror Grinding Kits - Details:



All 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. *Please note that chipping on the back side of the blanks at the edge is inevitable in our manufacturing process - always 1/4" or less, so they may be ground out with a 1/4" bevel. The front of the blanks will have no edge chips which will survive past your first 1/8" standard bevelling.

Mirror Kit Sizes:


We currently provide telescope mirror making kits in the following sizes:

4.3", 5.6", 6.1", 7.6", 8.4" - larger mirror kit sizes available VERY SOON - please tell your friends about us!

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.
