ABSTRACT:
A cylindrical body of a Newton reflective telescope includes a first cylindrical body and a second cylindrical body combined together. The first cylindrical body has an eyepiece fixed on an outer surface, and a reflective mirror fixed in its interior. A joint member is connected between the first and the second cylindrical body to enable the first cylindrical body to rotate relative to the second cylindrical body as a pivot in such a way that the first and the second cylindrical body have coincident center axes. Therefore, a person other than a first user can also look in the eyepieces by rotating the first cylindrical body without need for the first user to leave the location of the eyepiece.
