Unformatted text preview: 3.36 x 10-6 * (180/pi) * 60 * 60 = 0.69 arc seconds _________ 0.69 ___________________ arc seconds Notice the comparison of this value to the typical atmospheric resolution limits of 0.4 arc seconds (great mountaintop site) and about 1.0 arc seconds (good for an average astronomical site). What size on the image plane does this angle correspond to? (Express your answer in terms of micrometers.) y = f * θ = 1.2 * 3.36 x 10-6 = 4.032 x 10-6 ___________ 4.0 __________________ μ m Notice the comparison of this value to the typical size of a single pixel of a CCD sensor for a camera, about 3 to 8 μ m....
