Slow Newtonians need not be parabolized if the spherical aberration blur is smaller than the Airy disk. This is clearly shown in fig. 4. 025 mm. For the 200 mm Newtonian, a spherical mirror is acceptable for visual use in fl12 and slower systems; parabolizing is not needed for photographic instruments f/8 and slower.

1 Optical Layout of the Newtonian Telescope. 1 Introduction The Newtonian is the simplest and probably the most popular type of telescope for amateur astronomers. It is, without a doubt, the most commonly home-built amateur instrument. As such, the Newtonian is the de facto standard against which the performance of other types of telescope is measured. The Newtonian optical system consists of a paraboloidal (often mistakenly called "parabolic") primary mirror and a flat secondary mirror which directs the converging cone of light out of the tube for visual or photographic applications.

All four possible combinations of the tangential and sagittal focal surfaces have been drawn in fig. 11. Vertical lines are planes perpendicular to the optical axis. In cases 1 and 2, when the position of the tangential focal surface lies to the left of the sagittal focal surface, the system is said to have positive, or undercorrected, astigmatism. In cases 3 and 4, the astigmatism is negative, or overcorrected. Astigmatism is undercorrected for a single positive lens. 3: Chromatic Aberrations t s 31 s Image Height Fig.
