A stargazer has an astronomical telescope with an objective whose focal length is 180 cm and an eyepiece whose focal length is 1.20 cm. He wants to increase the angular magnification of a galaxy under view by replacing the eyepiece. Once the eyepiece is replaced, the barrel of the telescope must be adjusted to bring the galaxy back into focus. Since the new eyepiece shortens the original eyepiece focal length by 0.50 cm, what will be the new magnification the stargazer is now able to achieve?
