As with Lаb 5, we will use the simulаtiоn аt https://astrо.unl.edu/classactiоn/animations/telescopes/telescope10.html for this question. However we will observe the star cluster and thus select Cluster on the Target Option. Also make sure to use the Focus Adjustment to focus your image to the best view where the individual stars are in focus and appear as bright dots and not fuzzy lights. 1. Set the Aperture to 4-inch and the Eyepiece to 20 mm. There is a concentration of stars in the cluster. Answer the following questions, one per line in your Answer section: a. What value of Focus Adjustments brings the image into focus with little or no blurring? b. Increase the Aperture to 6-inch and keep the eyepiece the same. What (new) value of the Focus Adjustments focuses the image? c. Fully describe the changes in the image when changes to the aperture alone? Which values in the Readouts changes?  d. Now increase the size of the aperture to 8 inches and refocus. Change the value of the eyepieces and fully describe the changes in the image when changes are done to the eyepiece alone? Which values in the Readouts changes?  2. If you were searching for a particular star in this cluster, which combination of aperture (objective) lens and eyepiece lens would you choose? Fully explain your answer.
