Newtonian telescope secondary mirror. This design reduces the size and cost of the telescope with a shorter overall telescope tube length (with the corrector extending the focal length in a "telephoto" type layout) combined with a less costly spherical mirror. Commercially produced versions of this design have been noted to be optically compromised due to the difficulty of producing a correctly shaped sub-aperture corrector in a telescope targeted at the inexpensive end of the telescope market. Newtonian telescope The Newtonian telescope, also called the Newtonian reflector or just the Newtonian, is a type of reflecting telescope invented by the English scientist Sir
Galilean Galilean Zealots and Judean Pharisees. During the Great Rebellion (66-70 CE) the Galileans and Idumeans were the most adamant fighters against Rome; they fought the Romans to the death when many Judeans were ready to accept peace terms. Unlike the Judeans and the Idumean, the Galileans survived until the 1930s in the village of Peki'in, after which the Jews were expelled to Hadera by the Arab riots. Until 500 years ago, Peki'in had a Jewish majority and in Medieval times, Galilean Jews had presence in many villages such as Kafr Yassif, Biriyya, Alma, and more. "Galileans" (or "Galilæans") were also
