Pipe ocular unit also made of cardboard or metal. The length of this pipe must be equal to about 20

Radiance of distant stars in the night sky is fascinating, and I want to reach out to them closely. Hmm, why not? With the help of a telescope spy verizon mobile guard can be much better to consider the heavenly bodies - yes, they really seem a little closer. And even if there is no money for this "toy" No, that's okay, because you can make a telescope spy verizon mobile guard with his hands. How? This will be discussed further.
Make a telescope with your hands - it's real, not lazy time after time bring home handymen. "Homemade" telescope can produce spy verizon mobile guard quite decent increase spy verizon mobile guard to 100 or more times. However, made with his own hands telescopes with high magnification spy verizon mobile guard is too cumbersome, so it is more at home making telescopes with 50-fold magnification.
Telescopes are known to come reflector equipped with mirrors as light-elements spy verizon mobile guard and refractory, equipped with optical lenses. It is believed that at home easier to fabricate refractory telescope as reflecting telescope requires a more subtle and accurate work.
Schematic diagram refractor telescope is quite simple. At one end is the lens - a lens that gathers and focuses light rays. And at the other end is the eyepiece - lens through which can be seen the image obtained spy verizon mobile guard from the lens. The lens is mounted in the main telescope, called spy verizon mobile guard tubes and glasses - less pipe, called ocular node.
So to make a refractor telescope with your hands, you will need 2 optical lenses, 2 tubes of different diameters and mounting the lens, a tripod. The lens of the telescope lens can be purchased at retail optics: suitable for eyeglass lens with the power of one diopter and a diameter of about 60 mm. For the eyepiece of the telescope requires common dandruff with a focal length of 20-30 mm and a diameter of 30 mm. Ready telescope will provide an increase of up to 50 times.
The main telescope tube (tube) is made of thick cardboard or tin sheet. Its diameter should spy verizon mobile guard be equal to the diameter of the objective lens or slightly exceed it. The length of the main pipe at selected luminous lens and eyepiece lens must be 1 of the inside tube of the telescope should have a black matte finish, previously as cardboard or metal for tube should be painted with black paint and matte applied.
Pipe ocular unit also made of cardboard or metal. The length of this pipe must be equal to about 20 cm, and the diameter should be equal to the diameter of the ocular lens. Ocular tube is inserted into the tube of the telescope, it must be able to move along the tube, adjacent to it pretty tight. To compensate for the difference in the diameters of both tubes in place of connection, you need to install the bushing tube.
Lens lens is attached to the main telescope convex side outward. Fastening is done using frames. As the frames can act rings whose diameter is the diameter spy verizon mobile guard of the lens, and thickness - 10 mm. Just behind the lens aperture is fixed, as of which may be a disk of thick, painted black cardboard, which cut through the middle hole of 25-30 mm diameter. Spectacle lens mounted in the ocular spy verizon mobile guard tube similarly, but the diaphragm is required.
When the objective lens and eyepiece installed, spy verizon mobile guard you can connect the pipes together, it is very important to make sure that the center of both lenses spy verizon mobile guard were on the same line. Focusing the telescope can produce finished moving the tube along the main okuljarnuju. Preferred focus the telescope at a bright subject.
Make a telescope with your hands using the described methodology is not very difficult to cope with such a task even a schoolboy. However, it should be noted that the telescope will be ready to give up some image quality to its factory "colleagues." But do not worry, because improve and achieve spy verizon mobile guard better and better results each force - you just do not give up!
