The telescope was invented by a Dutch spectacle maker, Hans Lippershey (it is still unclear as to who the inventor of the telescope is, since there are many other contenders for the title but most reliable sources point to him.), it’s a common mistake to credit the invention of the telescope to Galileo, although he was the first person ever to observe the heavens, with a telescope, he did not invent it. The first application of the telescope was not the heavens as most had expected, however it was in the battlefield to observe enemy troop movements. As soon as Galileo heard the news, he was fascinated, and decided to fashion a telescope, for himself .The one he crafted was, by our standards” quite shabby”. It was no where near the precision that we have achieved today with our technology and advances in optics.
GalileoWe know that Newton made the all important modification of using mirrors instead of just lenses, to which he is still credited with the “Newtonian Reflector” a very popular telescope type today. We also have the Schmidt-Cassegrain, or Maksutov-Cassegrain telescopes which have the rare distinction of supposedly having inspired the maximum number of people to explore amateur astronomy owing to its portability and aperture and being cheaper than the refractors.
But the issue of availability of this instrument is quite another story, since the development of the telescope the production and manufacturing of the telescope has been in the hands of a limited few individuals and the market worth of these individuals is always determined by the quality of the Telescope they make, let me at this juncture make it explicitly clear that the perfect telescope does not exist. It all depends on the usage of that telescope for that particular observing session or the kind of heavenly bodies the observer finds most interesting..
