the reflecting telescope was!!
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.

A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.
A refracting telescope uses lenses to gather and focus light, while a reflecting telescope uses mirrors. Reflecting telescopes are often preferred for large astronomical telescopes because mirrors can be made larger and more easily than lenses.
Galileo turned a refracting telescope, which uses lenses to gather and focus light, skyward in 1610. This allowed him to make groundbreaking astronomical observations such as the moons of Jupiter and the phases of Venus.
Newton's first major public scientific achievement was the invention, design and construction of a reflecting telescope.
Sir Isaac Newton improved the design of the telescope by introducing the reflecting telescope in 1668. He utilized a curved mirror to gather and focus light, which helped eliminate the chromatic aberration issues present in refracting telescopes that used lenses. This innovation marked a significant advancement in telescopic technology, allowing for clearer and more detailed astronomical observations. Newton's design laid the foundation for many modern telescopes used today.
A Galilean Telescope is also an Astronomical Telescope so it is just a subset of Astronomical Telescopes.
Galileo Galilei didn't actually invent the telescope but he made vast improvements to the first design.
Yes, a Hershelian telescope is a type of reflecting telescope in which the primary mirror is tilted so the observer's head does not block the incoming light.
