Making a telescope is a very worthwhile experience because it crosses several areas of experience. The first reward for you is something fun to do. And the second reward is the sheer joy with which you explore the universe. And you can also obtain the additional benefits of saving some money and learning about telescopes and buildings things.
The simplest telescope you can
There are many different ways you and the absolute easiest way to make one, of only two lenses. A major objective lens called for a smaller and a second lens gives a eyepiece. They hold a lens near the eye lens and another in arms length. They fit the difference between the two, using your arm in the direction you. A point will be reached where everything comes into focus. It is as simple as that you have a telescope. Now you can get it much better by creating a tube around. Get two with cardboard tubes, which slide in and out the other. You mount a lens at the end of the tube and another lens on the other end of the tube. Insert a cane in the other and then push them in and out to focus.
You can get very cheap lenses from a variety of surplus and online shops and they are in general only costs a few dollars. I commend you for your primary lens of a convex lens at least 50 millimeters in diameter and a focal length of 200 to 300 millimeters. For the secondary lens I recommend you a convex lens, the 10 to 25 millimeters wide with a focal length of less than 75 millimeters.
There are several things you can do to this telescope even better. First of all, you could have a hose from something more durable than cardboard tubes. Secondly, this type of telescope images will invert it seems everything upside down, which is fine for viewing the sky, but is very unfavourable for the display things on the earth. You can solve this problem by using a concave lens for the eyepiece, rather than a convex lens.
You can purchase the lenses individually surplus of online shops and there are several kits available to you all the necessary materials to this type of telescope . In addition, they are in bulk units for the teaching and group. A kit like this rule, you receive all necessary materials to ten or more telescopes.
