A Newtonian Telescope

Everybody is curious about the stars in the sky. So, let's begin our DIY to build our Newtonian Telescope.

For basic ABCs, you might google "Newtonian telescope".

This project may last for a month long, from 1st March to 31st March, 2017.
(2017.3.14) I have printed all the parts uploaded, the next step is assembling them together. Currently, in my mind, the most difficult tast would be the adjustment of the light path.
