PARTIAL TELESCOPE KITS
FOR SCHOOLS

The BYOT (Build Your Own Telescope) Kits have changed to enable schools to buy only the components they need. The Teachers Instruction Notes can be purchased separately which includes a information background on all the science, maths and instruction for making the Main Mirror. There are many web sites which have instructions on how to build the rest of the telescope. Here is one of the better ones:
