Digital Imaging for the Introductory Astronomy Laboratory

基于使用CCD相机和计算机辅助分析的数字图像采集技术，正在为天文学101-102实验室开发一系列动手实验练习。这些实验室为学生提供拍摄天文图像的实践经验，并教授他们从这些图像中提取信息的各种方法。五个核心练习最初被开发，逐渐扩展和额外的练习被添加，直到在两个学期序列的24个实验室练习中至少有一半涉及新技术。以下是最初的五个核心练习(1)数字成像导论，(2)月球表面特征，(3)变星光曲线，(4)M67的HR图，(5)星系图像。重点是学生的参与和充分利用当前的图像收集和处理，提供了一个冷却CCD相机和配套的计算机和电子硬件。

A series of hands-on laboratory exercises for Astronomy 101-102 labs is being developed based on the techniques of digital image acquisition using CCD cameras and computer aided analysis. The laboratories give students hands-on experience in taking astronomical images and teach various ways in which they can extract information from these images. Five core exercises are being developed initially, with gradual extensions and additional exercises being added until at least half of the two dozen laboratory exercises in the two semester sequence involve new technology. The following are the initial five core exercises (1) An Introduction to Digital Imaging, (2) Lunar Surface Features, (3) Light Curve of a Variable Star, (4) HR Diagram of M67, and (5) Images of Galaxies. Emphasis is be on student participation and the full utilization of current image collection and processing as provided by a cooled CCD camera and supporting computer and electronics hardware.
