My astronomy project:
Design a Newton telescope

I stumbled into this when I found the great Newton design tool:

• https://stellafane.org/ tm/newt-web/ newt-web.html
  (Newton telescope Web design tool by Kenneth H. Slater, math and physics by Dale Keller)

With this tool you can very easy find what demand you should have of the components of a Newton telescope.

I have never done this before so it's a trail and error process. And I don't think I ever will built a telescope from scratch, just more to collect information and knowledge what to look after when buying a telescope.

Note:
Don't build a telescope after my ideas before you know by yourself that it will work. Otherwise you will waste a lot of time and money!

My first attempt to design a Newton telescope.

Here you also find instructions how to use Newt-Web.

Here I try to help a friend to find the basic construction of a very big visual Newton telescope.
