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 dialect century. Hugo Odeberg attempted a grammar based on the Aramaic of the Genesis Rabbah in 1939. Michael Sokoloff's English preface to Caspar Levias' Hebrew language "Grammar of Galilean Aramaic" (1986) also sheds light on the controversy that began with Dalman. Edward Kutscher's "Studies in Galilean Aramaic" (1976) may offer some newer insights. More recently attempts to better understand the Galilean dialect vis a vis the New Testament have been taken up by Steve Caruso. Evidence on possible shortening or changing of Hebrew names into Galilean is limited. Ossuary inscriptions invariably show full Hebrew name forms. David Flusser suggested that the
