New page

A Newtonian telescope is a type of reflecting [[telescope]] where a large single parabolic mirror acts as the objective. The light from the parabolic mirror is reflected out the side at the top of the telescope to where it comes to a focus and may be observed.

		+	Sir Isaac Newton invented the Newtonian telescope in 1668. <ref name="freedman">Freedman, Roger; Geller, Robert; Kaufmann III, William <u>Universe</u> 10th ed. </ref> Of the reflector designs the Newtonian is the simplest as only one optical surface needs to be ground. The secondary mirror is simply a flat mirror held at a 45 degree angle in front of the primary mirror.
		+
		+	This design simplicity has made the Newtonian not only the oldest reflecting telescope design, but a very popular one with amateur observers. In general terms a Newtonian telescope will be the least expensive per unit aperture than other types of telescope. The simplicity also allows many amateur astronomers to build their own telescope.
		+
		+	The Newtonian isn't particularly popular with professional astronomers as larger telescopes with longer focal lengths become unwieldy as the eyepiece and sensor mount are at times high above the ground.
