Looking for a very first telescope? But don't want to spend the money yet. Or looking for a telescope for a child or young person. Yet you want one that actually performs well. Celestron (Which is a premiere telescope making company) has an outstanding telescope at an extremely affordable price. I highly recommend this scope if you know almost nothing about telescopes yet want to try it without spending much money. I have more information about the Celestron FirstScope here
If you are able to spend a little bit more money I recommend you try this telescope. It is a bit better
Celestron 21061 AstroMaster 70 AZ Refractor Telescope This is a a well made telescope with terrific optics. You can use it for astronomical viewing or terrestrial viewing. The mount is very stable which is important. The company is one of the premiere companies for telescope making. The important thing here is that you get really good value for your money. I recommend this one also if you don't know much about astronomy and just want to get a good experience without breaking the bank. This is not like those cheap telescopes you can buy in the store. They always have very shaky mounts and inferior optics - not this one. Just check out all the 5 star reviews on amazon.

New: Newtons Telescope - You might be familiar with Galileo's telescope. He is generally credited as creating the first refractor telescope that was used for astronomical observation. I do have an essay on Galileo's Telescope here . But you might not be familiar with the First telescope that was made with a mirror rather than lenses. That telescope is now called the Newtonian after its early adopter. Newton didn't invent the reflector telescope.It was invented by an Italian Monk Physicist, and Astronomer named Niccolo Zucchi . But Newton did simplify the design and build one (The actual telescope he built is shown in the photo at left). He built this telescope sometime shortly before 1670 and it first became known when he described it to the Royal Society in 1670. There is a company that has replicated this beautiful telescope. Take a look at it here: Vixen 34031 Replica Newtonian Telescope (It's quite a beautiful newly updated rendition.)

Passionate about Telescopes
I want to applaud your interest in astronomy and telescopes. Making and using telescopes has been a passion of mine for a very long time. This is an old picture of me with the first telescope I made. I thoroughly enjoy the hobby and I know that you will enjoy it too. It will bring a lot of enrichment to your life as it has done with mine.
Galileo is often thought of as inventing the telescope. He didn’t invent the telescope but he was the first person to turn one toward the night sky. And the observations he made created the new science of modern astronomy where telescopes are used to help us understand our universe, our place in it, and how it works.
Galileo first heard about the mysterious telescope in 1609 and set out to make a copy for himself. This first telescope magnified images about three times. And over the course of a decade Galileo continued to make more telescopes and his most powerful one magnified images about ten times. This telescope enabled him to see things never before seen. And it enabled him to change our view of the universe and of the objects in the sky. If you want to read more about Galileo and his telescope I have a great article here.
