Once he had some lenses and got the idea,
he could probably have done it in an hour.
Aristotle did not invent the telescope; he lived roughly 2000 years before the telescope was invented.
The Hubble Space Telescope took about a decade to build, from the time its construction was initiated in the 1970s to its launch in 1990. Various delays and setbacks extended the construction timeline.
Ptolemy did not invent the telescope; the invention of the telescope is attributed to the early 17th century. The first recorded telescope was created in 1608 by Hans Lippershey, a Dutch spectacle maker. Ptolemy was a Greek astronomer and mathematician who lived in the 2nd century AD, long before the invention of the telescope. His work primarily involved the geocentric model of the universe rather than optical instruments.

The invention of the telescope is generally attributed to Hans Lippershey in 1608. The first practical telescopes were developed by Galileo Galilei in 1609. So, telescopes have been around for over 400 years.
Construction began in 1977 and it was ready for launch in 1985, around eight years later. It was not launched until April 24, 1990 though, due to delays from the Challenger disaster in 1986.

There were reports that the Bolognese Cesare Caravaggi had constructed one around 1626 and the Italian professor Niccolò Zucchi, in a later work, wrote that he had experimented with a concave bronze mirror in 1616, but said it did not produce a satisfactory image
The telescope has been used for over 100 years!!!
