Hindus have traditionally worshiped the Navagrahas, or the nine celestial bodies (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu) in Hindu astrology, through rituals and offerings, such as pooja and havan, which do not require the use of a telescope. The invention of the telescope in 1609 by Hans Lippershey did not affect the traditional methods of worshiping the Navagrahas in Hinduism.
In Hinduism, the Navagrahas are considered to have a significant impact on an individual's life and are believed to be responsible for bringing both positive and negative effects. Worshiping the Navagrahas is believed to help appease them and reduce the negative effects they might bring.
The traditional methods of worshiping the Navagrahas include performing pooja, which involves offering prayers, lighting lamps, and making offerings of flowers, fruits, and other items. Another method is performing havan, which involves the use of fire and offerings of ghee, grains, and other items. These rituals are typically performed by a Hindu priest and can be done at home or at a temple dedicated to the Navagrahas.
In addition to these rituals, there are also specific days of the week dedicated to each of the Navagrahas, and it is believed that worshiping them on these days is particularly beneficial. For example, Monday is dedicated to the Moon, Tuesday to Mars, and so on.
It should be noted that the telescope was not invented in Hindu culture and its invention does not have any impact on the traditional methods of worshiping the Navagrahas. The invention of the telescope has no connection with the traditional rituals and practices of Hinduism.
