Now that I am aware about what is a good telescope and what is not, I would not recommend you any overly cheap telescope because it has very bad perfomrances and unless you are really determind and really into astronomy, it can just make you disgusted by astronomy. But if you want a cheap one... Take a small dobson. Dobsons are a kind of telescope that is probably the most currently selled kind in our time. They are easy to use and simple to collimate. If you want you can buy a 100/400 dobson. This telescope is very tiny and will not make you see all the 7840 NGC objectrs, not even a half of it. But with this telescope you could see every 110 objects of Messier catalogue, Moon and Planets. It is a good starting. The only problem of a dobson for a beginner is that you need to colimate the telescope. you need to buy a cheshire. This is a tool to collimate your telescope. Colimation is the process to allign the mirrors of your scope. It can be scary but I swear this is easy. There are tutorials on internet. But if you want a simplier telescope to use, you can buy a 70/700 refractor. Refractors don't need a collimation. The only problem is that they are more expansive with same performances but can still be good to start.
Here are the scopes I recommand and are super cheap (so it wont make you awesome things, but can make you eventually buy a better telescope if you are interested by astronomy) :

Astroshop is based in Europe, but you can try to search for telescopes that will be send from your country or a close one. If you want even cheaper telescopes, then, here it is :

For this price I think this is maybe one of the best you can get.
Have fun, and don't forget to seek for informations. After buying a cheap telescope, if you want a better one, Buy a dob if you don't want something too expansive (Astronomy is an expansive hobby. A 8" dob can cost 400$ but it will offer you good performances). But over all, avoid buying telescopes on amazon. The only thing I bought from amazon was my collimator and it works good, but amazon can be bad sometimes. Don't buy a powerseeker. Their price is very low but trust me, these telescopes are shitty and all will appear blurry. Don't buy a powerseeker. And finally, read advices about a telescope you would want to buy. It is always helpful.
Then when you'll want to do stargazing, don't forget to collimate your telescope if it needs to be. Cool it down by putting it outside. for maybe 30 minutes if it is a small one, 1 hour or more if it is a big one.
You can stop to read from here because it is long as fuck but here are some infos to buy a scope :
70/700.
70 is the diameter of the telescope. The biggest, the better. Big diameter= more light entering in your scope=able to see more things.
700 is focal lenght. The biggest the focal lenght, the more you can magnify.
If you divide the focal lenght by the diameter, you will obtain a number. for example : 1000/100=10 anf you call this number "f/10" If this number is bellow 7, the scope is better to observe DSO (nebulas, galaxies, all the things that aren't in our solar system)
If this number is 10 or more, the scope is better to observe planets and close objects.
If this number is between 7 and 10 it can be good for both.
Take in note that of course you can observe planets with a F/5 but a F/10 wil work better.
How to choose your eyepieces :
If you multiply the diameter by 2, you will obtain the biggest magnification you can reach. If you multiply it by 1.5, you will obtain the optimal magnification. It is in theory the magnification that exploit the performances of your telescope the best. If you devide the diameter of your scope by 7, you will obtain the minimal magnification. you will obtain a number and this is how many times the telescope magnifies. Now to find your eyepiece, divide your focal lenght by the magnification you want. You will obtain the focal lenght your eyepiece need. If it is a number like 7,32, just try to get the closest you can.
Have fun with your scope! Clear skies !
