Astronomical imaging can provide excellent opportunities for undergraduate students to explore the science of astronomy, the process of scientific investigation, and the technology of imaging and image processing. Students are using a CCD camera attached to Grinnell's 0.61 m telescope to carry out a wide variety of observational programs and processing the resulting images on the observatory's Sun workstation using IRAF and other image processing software. Projects involve the study of relatively faint objects (galaxies, nebulae, and star clusters) and emphasize the extraction of physical information from the images through, for example, the use of filters during the exposures, and computer analysis of the resulting images. This instrumentation is used most heavily by physics majors who are doing one or two-semester independent study projects, but is also used in the general astronomy and advanced laboratory courses. The acquisition of a CCD camera system completes the process of development of image acquisition and analysis capability at Grinnell's observatory that has taken place over the past several years.

天文成像可以为本科生提供探索天文科学、科学调查过程以及成像和图像处理技术的绝佳机会。学生们正在使用连接在格林内尔0.61米望远镜上的CCD相机来执行各种观测计划，并使用IRAF和其他图像处理软件在天文台的Sun工作站上处理产生的图像。项目涉及对相对较暗的物体(星系、星云和星团)的研究，并强调从图像中提取物理信息，例如，通过在曝光过程中使用滤光片，以及对生成的图像进行计算机分析。这种仪器最常被物理专业的学生使用，他们正在做一两个学期的自主学习项目，但也被用于普通天文学和高级实验室课程。在过去几年中，格林内尔天文台完成了图像采集和分析能力的发展过程，获得了一套CCD摄像系统。
