大多数照片都没有充分地描绘出太阳日冕的壮丽。在日全食期间亲眼看到日冕是无与伦比的。人眼可以适应看到普通相机通常无法看到的冠状特征和范围。然而，欢迎来到数字时代。这张特色图像是在澳大利亚埃克斯茅斯拍摄的短曝光和长曝光的数字组合，经过处理，突出了2023年4月发生的日全食期间日冕中微弱和延伸的特征。清晰可见的是太阳日冕中不断变化的热气体和磁场混合物的复杂层和发光焦散。环状日珥在太阳边缘附近呈现出明亮的粉红色。在日全食前后几秒钟拍摄的照片显示了背景太阳的瞥见，被称为贝利珠和钻石戒指效应。下一次日全食将在2024年4月穿越北美。2023年4月日全食画廊：向APOD提交的重要作品

Most photographs don't adequately portray the magnificence of the Sun's corona. Seeing the corona first-hand during a total solar eclipse is unparalleled. The human eye can adapt to see coronal features and extent that average cameras usually cannot. Welcome, however, to the digital age. The featured image digitally combined short and long exposures taken in Exmouth, Australia that were processed to highlight faint and extended features in the corona during the total solar eclipse that occurred in April of 2023. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields in the Sun's corona. Looping prominences appear bright pink just past the Sun's edge. Images taken seconds before and after the total eclipse show glimpses of the background Sun known as Baily's Beads and diamond ring effect. The next total solar eclipse will cross North America in April of 2024. Total Solar Eclipse of 2023 April Gallery: Notable Submissions to APOD
