Sometimes one wants to watch the night sky, take a closer look at the stars or look at a flying comet, but there is no way to do this. Because telescopes are quite expensive. And we want to look at the stars only occasionally. There is a way out of this situation, you can assemble a telescope do it yourself.
Let's watch the video homemade:

The cost of assembling the simplest telescope of the Galileo system refractor was only $ 5.
To do this, you must:
- magnifying magnifier with a diameter of 100mm;
- a lens with a diameter of 25-50 mm, minus 18 diopters, we will use it as an eyepiece;
- a plastic pipe with a diameter of 100mm;
- plastic adapter;
- a small piece of automotive rubber pipe;
- two o-rings of different widths from a 100mm plastic pipe;
- adhesive tape;
- screwdriver;
- stationery knife;
- hammer;
- scotch tape.
So, all the necessary tools and material are prepared, you can proceed directly to the assembly of the telescope.
Two fasteners for open-laid plastic pipes are put on a piece of plastic pipe.
An excess detail is cut from a magnifying magnifier, i.e. handle, it will only interfere, the cut is carefully sanded. Next, a magnifying loupe in a plastic rim is wrapped with a narrow sealing gasket, which is made of the same sewer plastic pipe with a diameter of 100 mm. Because glass is slightly larger than the diameter of the gasket; an incision is made in it.
Then the magnifying glass together with the sealing gasket is carefully inserted into the plastic pipe, on which we put on the fasteners for the plastic pipes of the open gasket, so that it does not stick out. After that, one of the mounts rises to the level of the magnifying glass and is tightened on both sides with a screwdriver, so we fix the magnifying glass at the end of the pipe.
Then we need to attach a plastic adapter, which can be bought at any hardware store. We insert the remaining sealing gasket into the wide opening on the adapter, a pipe and magnifying glass construction is inserted into the gasket. With the help of a hammer, the gasket drops as deep as possible into the adapter.
We attach the eyepiece lens to a piece of automobile rubber pipe using tape around the entire circumference.
We insert this design into the narrow part of the plastic adapter, and is also fixed with adhesive tape.
A second mount for the plastic pipes of an open gasket is used to secure the assembled telescope to a convenient pole or stick.
