Unformatted text preview: Maksutov Catadioptric Telescope It is desired to configure a telescope for astronomical observations. A 3 . 5 inch di- ameter, 1300 mm focal length, f/ 14 . 4 Questar brand Maksutov catadioptric telescope is available. It may be used with either of two eyepieces that have specfications as follows: 1) a 26 mm focal length Koenig eyepiece with an apparent field-of-view of 50 or 2) a 12 mm focal length Erfle wide-field eyepiece with an apparent field-of-view of 75 . The apparent field-of-view is the full apex angle of the light exiting the eyepiece as seen by the human observer. Calculate, showing all work, the angular magnification of this telescope obtained with each of these eyepieces. Express your answers accurately to three significant figures. Put your answers in the spaces provided. Angular magnification with Koenig eyepiece = X Angular magnification with Erfle eyepiece = X Calculate, showing all work, the true field-of-view (as measured in the sky) of this telescope obtained with each of these eyepieces. Express your answers in degrees accu-telescope obtained with each of these eyepieces....
