Building a Telescope At Home: Is It Possible?

Building a Telescope At Home: Is It Possible?

Believe it or not, humanity has not always had powerful telescopes capable of observing the depths of the Cosmos. At first, humanity was able just to see a few planets nearby, such as Jupiter, Saturn, or Mars. Later on, after decades and centuries of scientific work, many powerful telescopes were developed. Therefore, humanity has been able to observe remote planets, stars, and galaxies in all their splendor.


But did you know that it’s not mandatory to head over to in Space Observatory to see a few planets in real time? That’s because you can build your own telescope at home if you have the materials needed. Stargazers have the chance to feast their eyes on a few celestial objects from the comfort of their own home comma, as all they have to do is take into account the steps that we’ll be talking about below.


Materials needed:


Two convex lenses, a larger one will be needed for the objective lens in the spot or one for the IPS;

Cardboard tubes or PVC pipes will be needed for the telescope body.

Cardboard or wood comma which is needed for constructing the lens mounts.

Tape or glue

A ruler or measuring tape 

A knife or scissors


Here is this step-by-step guide:


Choose lenses:


 The first step is to select two convex lenses. You can use lenses salvaged from a pair of old binoculars or cameras, or you can even purchase them from a hobby store. The objective lens that comes out, which is the larger one, should have a longer focal length compared to the eyepiece lens.


Determine focal lengths
The next step is to measure the focal length of both lenses. You can do so by simply holding each lens the distant objects and adjusting the distance until the image looks sharp.
Build a telescope body:
Constructing the main body of the telescope isn’t as hard as it seems, as for the first part, you need to use cardboard tubes or PVC pipes. The length of the tubes will depend on the focal lengths that the lenses have. You need to know that the longer tube should accommodate for objective lens has the shorter tube to hold the eyepiece.
Mount the lenses: 
The fourth step is to create some mounts for the lenses. You can do so by taking advantage of cardboard or wood. You need to cut out most likely smaller than the diameters of the lenses I make a hole in the center for the lenses to fit snugly. You will have to attach these mounts to the ends of the telescope tubes.
Insert lenses: 
For the fifth step, you will have to place the objective lens meaning the larger one, at the far end of the telescope tube. You need to make sure it is securely mounted. Feel free to insert the eyepiece lens, meaning the smaller lens, into the other end of the telescope tube.
Adjust and test
And I know for sure if something is should be unless you put it to the test, and it also applies in this case. Therefore, you need to experiment with the distance between the lenses to a you have to slide the eyepiece in and out of the tube until the image appears sharp. go ahead and secure the IPS in place once you find the optimal position.
Finish the construction:
If you’re satisfied with the focus you need to secure all components in place with tape or glue. Make sure that the lenses are aligned as they should be and that the telescope body is sturdy.
Congratulations, your telescope should be done if you have followed the steps mentioned above! This means that you can feel free to take your telescope outside on a clear night and point it towards the heavens.
