Question:
Galileo’s best telescope had an eyepiece of -40 mm focal length, along with a biconvex objective about 30 mm in diameter. That objective formed real intermediate images of stars roughly 120 cm down the tube. Determine the magnification of that instrument and the focal ratio (ƒ/# ) of its objective.
