Make your own telescope ( with image erecting feature)

Making a telescope is easy but most of the time the image we get to see is inverted in an astronomical telescope. It not suitable for watching anything terrestrial and in this video, we will make a telescope which has image correction feature so that we use it to see things on the land as well.
I am using a Schmidt- Pechan Prism taken from a monocular to add this image erection feature. There are numerous ways to do it, but this is what I could come with.
Most of the supplies can be found in your local stationery, so you can make it too.

I guess, it not in focus and the image is getting smudged and thus thus looking overly bright. Try and focus something on the ground.(image will be inverted in your case though)Once you get a good grip on focus ability .. then start looking at the moon. Sometimes you may need to increase or decrease the length of the scope as well.

Thanks Kiddo. To make a telescope, look for two magnify glass. One Big and one small. The small one is usually higher in magnification. Place the big one away from you and the smaller one closer to eyes . start moving the bigger piece closer or farer to get the focus of the image. the image is usually inverted and this might be a little tricky. To invert the image you can use Schmidt -Pechaan prism or porro- prism. This prism is hard to find and you can get one form mobile zoom lens . Do you want amazon links?.

[@murali9649]

For telescopes, magnification of the objective and eye piece are not measured. The magnification of the telescope itself is measured as focal length of objective ÷ focal length of eye piece. This also hardly matters in astronomical telescopes, because the eye pieces can be changed as we wish. So the diameter of the objective is taken ( as it indicates the light collecting capacity of the telescope).
