摘要
使用北京天文台兴隆观测站60cm望远镜对10个旋涡星系进行CCD照相观测,通过对图像的处理及利用彭秋和提出的方法。
CCD images of 10 spiral galaxies were obtained with the 60 cm telescope at the Xinglong Station of Beijing Astronomical Observatory. After processing the images with computer and following Peng's method, we derived some important physical parameters (the scale heights of disk and inclinations, and so on) of these galaxies.
