简介： The Horsehead Nebula。A reproduction of a composite colour image of the Horsehead Nebula and its immediate surroundings. It is based on three exposures in the visual part of the spectrum with the FORS2 multi-mode instrument at the 8.2-m KUEYEN telescope, part of ESO\'s Very Large Telescope, at Paranal. It was produced from three images, obtained on February 1, 2000, with the FORS2 multi-mode instrument at the 8.2-m KUEYEN Unit Telescope and extracted from the VLT Science Archive Facility . The frames were obtained in the B-band (600 sec exposure; wavelength 429 nm; FWHM 88 nm; here rendered as blue), V-band (300 sec; 554 nm; 112 nm; green) and R-band (120 sec; 655 nm; 165 nm; red). The original pixel size is 0.2 arcsec. The photo shows the full field recorded in all three colours, approximately 6.5 x 6.7 arcmin 2 . The seeing was about 0.75 arcsec. This image is available as a mounted image in the ESOshop. 马头星云及其周围环境的合成彩色图像的复制品。这是基于8.2米KUEYEN望远镜的FORS2多模仪器在光谱视觉部分的三次曝光，该望远镜是ESO位于巴拉那的超大望远镜的一部分。它由2000年2月1日在8.2米KUEYEN单位望远镜上使用FORS2多模仪器获得的三幅图像制作而成，并从VLT科学档案馆提取。在B波段（600秒曝光；波长429 nm；FWHM 88 nm；此处呈现为蓝色）、V波段（300秒；554 nm；112 nm；绿色）和R波段（120秒；655 nm；165 nm；红色）获得帧。原始像素大小为0.2弧秒。照片显示了以所有三种颜色记录的全场，约为6.5 x 6.7 arcmin 2。视觉约为0.75弧秒。此映像在ESOshop中作为挂载映像提供
