Materials

I have also been thinking about possible materials that I can use for my final model. After discussion with my tutor Craig, we decided plastic may be a good way to go. This is because the material will look sharp, form a tube easily and slide easily as the tubes need to slide in and out from each other. One tube must be smaller than the other. I brainstormed many different types of metal and this seems to be the best one to try so far. I may need to paint the inside of the plastic black though so the light doesn't interfere with the vision of the telescope.
