Why do objects that formed from the same cloud of gas […]
Consider the advantages and disadvantages of different planetarium projection systems. In particular, compare and contrast systems which use spherical mirrors vs. the more traditional wide angle slide projectors. Include factors such as clarity, ease of use, and cost in your comparison. Which system do you believe is the best for planetarium programs?
After reading the article below as well as the weekly readings, write a 2-3 page comparison of Optical, Digital, and Laser Projection Systems. At the end, include a paragraph reflecting on what you learned and which system you feel is the most advantageous for planetarium use. While you will use this article for reference, be […]
