Many people, raising their eyes in the starry sky, admire the mouncing mystery of the outer space. I want to look into the endless expanses of the universe. See crater on the moon. Rings Saturn. Many nebulae and constellations. Therefore, today I will tell you how to make a telescope at home.
First, you need to decide what an increase is required. The fact is that the more this value, the longer the telescope itself is. With a 50-touch increase, the length will be 1 meter, and for 100 multiple - 2 meters. That is, the length of the telescope will be directly moving multiplicity.
Suppose it will be a 50-telescope. Next you need to purchase two lenses in any salon (or on the market). One for eyepiece (+2) - (+ 5) diopters. The second - for lens (+1) diopter (for 100 multiple telescope required (+0.5) diopter).
Then, given the diameters of the lenses, it is necessary to make a pipe, or rather two pipes - one must go into another tight. Moreover, the length of the resulting structure (in the proportion) should be equal to the focal length of the lens. In our case, the 1meter (for the lens (+1) diopter).
How to make pipes? To do this, it is necessary to wind several layers of paper on the rim of the corresponding diameter, sculpting them with epoxy resin (can be other glue, but the last layers are better to strengthen with epoxy). It can be used by the remnants of the wallpaper that are lying without a business after repairs. You can experiment with fiberglass, then it will be a more serious design.
Next, we embed to the outer tube lens lens (+1) diopter, and in the inner eyepiece (+3) diopter. How to do it? Your fantasy is the main thing to ensure accurate parallelism and alignment of lenses. It must be achieved that the distance between the lenses when the pipe is splenning was within the focal length of the lens lens, in our case it is 1 meter. In the future, with the help of changing this parameter, we will customize the sharpness of our image.
For convenient use of the telescope, a tripod is needed for a clear fixation. With a strong increase in the slightest jitter of the pipe leads to the erosion of the image.
If you have any lenses, you can find out their focal length in the following way: focus the sunlight on a flat surface until it can get as a smaller point. The distance between the lens and the surface is the focal length.
So, in order to achieve an increase in the telescope in 50 times, a lens in (+1) diopter is located at a distance of 1 meter from the lenses (+3) diopter.
For a 100 multiple zoom, use lenses (+0.5) and (+3) by changing the distance between them 2 meters.
