A set of allsky camera images from latitude 55 degrees North

A set of R G and B images from an allsky camera situated in Copenhagen, Denmark. The images have been darksubtracted and split into these 16-bit FITS format images. Each image is the sum of something like 9 PNG images which each, originally, were 14 bit images from a ZWO camera cmos detector.

本数据集收录了位于丹麦哥本哈根的一台全天空相机（allsky camera）采集的R、G、B三通道图像。该批图像已完成暗场扣除处理，并被转换为16位FITS格式（FITS）图像。每张最终图像均由约9张PNG格式（PNG）图像叠加求和得到，而这些PNG图像最初均为ZWO相机CMOS探测器（CMOS detector）采集的14位图像。
