简介： Messier 78: a reflection nebula in Orion。This new image of the reflection nebula Messier 78 was captured using the Wide Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile. This colour picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through a filter that isolates light from glowing hydrogen gas. The total exposure times were 9, 9, 17.5 and 15.5 minutes per filter, respectively. 这张反射星云梅西耶78的新图像是使用智利拉西拉天文台MPG/ESO 2.2米望远镜上的广角成像仪相机拍摄的。这张彩色照片是通过蓝色、黄色/绿色和红色滤光片拍摄的许多单色曝光，再加上通过滤光片的曝光，滤光片将光与炽热的氢气隔离开来。每个过滤器的总暴露时间分别为9、9、17.5和15.5分钟
