This chapter aims to illustrate all the concepts described through four case studies. Two involve sky-priority images; two involve foreground-priority images. Each case study integrates the foundations of astronomy and photography described in this book along with specific information obtained from our planning tools. The first case study is about Orion Over Mt. Whitney and through Mobius Arch. Mobius Arch is an iconic landmark of California's Alabama Hills in the Eastern Sierra. popularized by David Muench and Galen Rowell, it features a view of Mt. Whitney, the tallest mountain in the continental United States, through its graceful portal. One day, unfortunately, the morning sky quickly brightened and Orion slipped into obscurity. The author made repeated attempts over the next several years to create this photograph.
