An example of this is the Celestron NexStar 130SLT.

The image could therefore be viewed from behind the telescope, and not from the side, as with Newton’s design.

A Newton telescope will buy you more observing performance than any other telescope.

The principle behind Newton’s telescope was so simple that we still use it today.

For a sometimes lower price you can also buy a small Dobsonian (it looks like Newton’s telescope) from 150 to 200 mm in diameter.

See the world from a whole new perspective with this National Geographic 114 x 500mm Newtonian reflector telescope.

Henry Draper, one of the very first American astronomers to build a telescope, used a full reflection prism two centuries later instead of the plane mirror of the Newton telescope.

Herschel eliminated the small diagonal mirror of a standard newtonian reflector from his design and instead tilted his primary mirror so he could view the formed image when he stood in an observing cage directly in front of the telescope.

The image could therefore be viewed from behind the telescope, and not from the side, as with Newton’s design.

If you are older (e) you can buy a Newton telescope from 110 to 150 mm in diameter equipped with an equatorial mount.

Modeling of the telescope by an afocal system of two thin lenses and modeling of a Newton telescope with a mirror system, thin lenses :

For a sometimes lower price you can also buy a small Dobsonian (it looks like Newton’s telescope) from 150 to 200 mm in diameter.

A Newtonian reflector with a 6 inch (150mm) mirror will give you good views of the brighter galaxies and nebulae, and should also perform well when looking at the Moon and planets.

A Newtonian reflector with a 6-i nch (150mm) mirror will give you good views of the brighter galaxies and nebulae, and should also perform well when you train it on the Moon and planets.
