EXPERTS CAN YOU PLEASE TELL ME ABOUT THE NEWTONIAN AND THE GALLILEAN TELESCOPES. PLEASE ANSWER IT FAST AS SOON AS POSSIBLE !

Dear student, 1. A Galilean refracting telescope uses a concave lens as the eyepiece and is typically fixed focus and has a limited field of view. 2. A reflector collects light at one end of a tube and reflects it off a concave mirror. It is brought to a focus by a secondary mirror further up the tube at a 45 degree angle which is then magnified using an eyepiece. This type of reflector is called a Newtonian reflector. Regards
