(i) The telescope which is shown in figure is named as Newtonian telescope of reflecting.
(ii) The following are the key components of the telescope:
1. The Tube Assembly: The Tube Assembly is the long white portion that houses the mirror, secondary mirror, eyepiece, and holder. It refers to the entire optical system.
2. The Mount assembly : This refers to the entire system that holds and moves the telescope tube.
3. The eyepiece assembly consists of a focusing knob and a sleeve into which various sized eyepieces can be inserted.
4. At this end of the tube, the primary mirror collects all of the light and reflects it back up toward the eyepiece.
5. The counterweight: This is a large (black) weight that may be pushed up and down on the silver bar to balance the telescope and make it easier to use.
