The diameter of the full Moon in the focal plane of an average amateur's telescope (focal length 1.5 meters) is $13.8 \mathrm{mm}$ How big would the Moon be in the focal plane of a very large astronomical telescope (focal length 250 meters)?

Step 1
First, we need to find the magnification of the amateur telescope. The magnification can be calculated using the formula: Magnification = Focal length of the telescope / Focal length of the eyepiece Show more…

How large an image of the Moon will be formed by the 3.6-m-diameter mirror of the Canada-France-Hawaii Telescope, which has a focal length of 8.5m? When viewed from Earth, the Moon subtends an angle of 0.5° in the sky.

Viewed from Earth, the Moon subtends an angle of $0.5^{\circ}$ in the sky. How large an image of the Moon will be formed by the $3.6-\mathrm{m}-$ diameter, 8.5 -m-focal-length mirror of the Canada-FranceHawaii Telescope?
