The Newtonian Telescope.
A refractor telescope uses lenses to gather and focus light, while a reflector telescope uses mirrors to collect and concentrate light. Refractor telescopes tend to be more expensive and have less light-gathering capability compared to reflector telescopes. Refractors are also generally easier to maintain and have a sealed tube, making them less affected by dust or dirt.

Mercury is the most unlikely to be viewed because of its proximity to the sun, but it can be viewed with special equipment, like a light filter. All outer planets can be viewed with a telescope depending on the planets position relative to Earth.
With a telescope yes.
the scientist viewed the stars with his brand new telescope.
Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.
Ah, hello friend! Imagine a refractor telescope like a magic wand that uses lenses to bend and focus light coming from distant objects like trees or galaxies. By gathering all that light and bringing it into focus, we magnify the image to make it appear closer to our eyes - just like zooming in to see the fine details on a beautiful little squirrel or bird in the woods. Remember, the true magic is in seeing the beauty and wonder all around us, whether we view it up close or from afar.
Planets viewed through a telescope typically appear as small, round discs with some surface features visible. They may also show distinct colors, such as the reddish hue of Mars or the white clouds of Jupiter. The larger planets, like Jupiter and Saturn, can also reveal their moons as tiny specks of light nearby.
By using a Reflective telescope the viewer sees the image of a normal telescope, reflected on a mirror, which is viewed through a microscope, by doing this the telescope doubles it's viewing ability

the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
Neptune appears as a small, bluish dot when viewed from Earth. Its angular size varies depending on its distance and position relative to Earth in its orbit around the sun. On average, Neptune's angular diameter is about 2.3 arcseconds when viewed from Earth.
