Details

Do you want to build your own telescope? While it may seem like an impossible task to complete on your own at home, it really is very possible to make a top quality instrument that can even surpass many telescopes that you can find at a store. A 4.25 inch aperture telescope is a great size for beginning and experienced amateur telescope makers.

The first and key piece that you will need to make for your telescope is the primary, or objective, mirror. You will grind your mirror blank with smaller and smaller abrasives until you have produced a spherical or paraboloidal surface. Once the final polishing and testing steps are completed you will send your mirror off to receive a reflective coaiting. The process takes some time and patience but through a little knowledge and the law of averages you will produce an excellent telescope mirror.

This kit includes your telescope mirror blank and all the abrasives, polish, and pitch needed to grind, figure and polish your telescope mirror. If you do not have the materials ready at home to build your own grinding tool we can also supply a grinding tool kit. We also carry a variety of books that can teach you the full process if you need instruction.

Before long you will be up late at night discovering the universe through a top quality instrument made by your own hands!
