Given a telescope with an angular field of view of 6′×6′ recorded by a CCD chip having 1024×1024 pixels. What is the angle on the sky corresponding to 1 pixel? A) 0.35′′×0.35′′ B) 0.006′′×0.006" C) 6′×6′ D) 9.5e−5′′×9.5e−5′′ 7) [6 Points] Suppose you have a Cassegrain telescope that has a primary mirror of 200 mm diameter and a primary focal length of 2000 mm and you want to study the moon using a Ploessl eye-piece (apparent angular field of view of 50∘ ). What should be the focal length of the eye piece to guarantee that the moon (angular diameter 0.5∘ ) fit exactly in the field of view. A) around 10 mm. B) around 20 mm. C) around 30 mm. D) around 40 mm. E) around 50 mm.
