Theory One significant telescope property is magnification (Mag). Magnification makes a small object appear larger. If Mag = 30X, the image is 30 times the size of the object. Related to Magnification is Field of View (FOV). FOV measures the fraction of the sky that can be viewed by the instrument. Generally, the higher the Mag, the lower the FOV. Light Gathering Power (LGP) is a measure of the light collection efficiency of the telescope. The higher the LGP, the brighter the image. LGP varies with the area (or diameter squared) of the aperture. Resolution (Res) measures the ability of the telescope to bring out fine detail. Res varies with aperture diameter. Also, Res is better for higher frequency (blue) light than for lower frequency (red light). Notice in Figure 9-1 for the Refractor that Objective focal length (fobj) and eyepiece focal length (feye) are labeled. The lens separation in this type of Refractor is feye + fobj. The magnification is fobj / feye. Questions. (3.…

Galileo’s telescopes were not of high quality by modern standards. He was able to see the moons of Jupiter, but he never reported seeing features on Mars. Use the small-angle formula to find the maximum angular diameter of Mars when it is closest to Earth. How does that compare with the maximum diameter of Jupiter? (Note: Useful data can be found in Appendix Table A-10.)
