The Telescope

The History
Later on, in 1733, Chester Moore Hall created the achromatic lens, which reduced color abberations, and made it possible to make shorter telescopes. Although hall created the achromatic lens, John Dalland comercialized it, because hall did not release to the public.
These are only the earlier models though. The modern telescope design was created in 1910, but it wasn't very accepted until about 1950. This design is a very good design and even the Hubble Space Telescope uses it 50 years later, being able to look at distant galaxies.
Technical Information About the Telescope
Smaller, more portable telescopes can see a small, not very detailed version of planets and close stars. They usually don't offer that much information, and don't work when it is daytime or too cloudy, but are easier for a family to afford and store.
Larger, room-sized telescopes are many times more powerful than these smaller telescopes, offering images of distant stars and planets in our solar system. Some can even see other solar systems, but like the more family-oriented telescopes, they don't have very clear visibiltity in the daytime or when it is cloudy.
The best, but most expensive telescopes are telescopes that are deployed into orbit around the Earth and can see very detailed images of far-off galaxies, supernovas, black holes , and much more. The most known of these is the Hubble Space Telescope which has produced many very helpful, and amazing images.
Pros and Cons
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~CONS - The only con I can really think of is the fact that the telescope is basically what fueled the exploration of space and people have died for the exploration of space like the crew of Apollo 1.

Science:
A convex lens and a concave eyepiece interact with each other, in order to bend light in a way that expands an image.

Technology: Make a device that makes objects that are miles and miles away look like they are right next to you.

Engineering: Designing a compact enough way to see far into space, whilst also keeping the price tag low enough to afford.

Math: How thick or thin do we need to make the cuts in the lense and eyepiece in order for them to zoom properly? What are the dimensions of the telescope itself? How big should the eyepiece be so that you can fit you eye on it without trouble.
