Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
Yes.

The best place for astronomers to build their telescopes is a cold, dry, and calm place. Astronomers identified a place in the Antarctic that they believe is the best place for an observatory. Read more about it at http://phys.org/news170932769.html.
A reflecting telescope is much easier to build than a refracting telescope and consequently is much less expensive. A reflecting telescope uses a concave mirror to collect and concentrate starlight and send it to your eye, whereas a refracting telescope uses a series of lenses to do the same thing. Optical quality lenses are much more expensive (and heavier) than a well-made mirror. For a given amount of money, much larger reflecting telescope can be built than a refracting. For very large telescopes, the lenses needed would be enormous and next to impossible to make optically perfect. Consequently, most telescopes are reflecting.
That's a simple question, As more big businesses and new material /better material to build telescopes have come out the telescopes start to improve, scientists found that there are different combinations that enhance the viewing of telescopes. I don't get why'd you ask this, i could answer it easy and im 13 as its common sense. WOW your brainy!
Sky-Watcher sells a large variety of telescopes. These telescopes range greatly in price and options. It is a good idea to investigate the various telescopes they offer, many are labeled perfect for beginners.
Hundreds.
