业余望远镜的超深成像
Ultra-deep imaging with amateur telescopes
摘要：
业余小型设备已被证明是获得附近大质量星系外围超深成像和以前所未有的深度调查广阔天空的竞争工具。在过去的十年中，业余数据首次揭示了附近大质量星系周围各种各样的大规模潮汐结构，并在局部宇宙中发现了迄今未知的低表面亮度系统，这些系统迄今为止还没有通过分辨恒星星族或HI调查发现。在本星系群中，用长焦镜头拍摄的麦哲伦星云的低分辨率深层图像发现了一些类似贝壳的特征，被解释为最近LMC-SMC相互作用的印记。在这篇评论中，我讨论了这些亮点和其他重要成果，迄今为止，在这种新型的合作之间的高级天文摄影师和专业天文学家在星系形成和演化的研究课题。
英文摘要：
Amateur small equipment has demonstrated to be competitive tools to obtain ultra-deep imaging of the outskirts of nearby massive galaxies and to survey vast areas of the sky with unprecedented depth. Over the last decade, amateur data have revealed, in many cases for the first time, an assortment of large-scale tidal structures around nearby massive galaxies and have detected hitherto unknown low surface brightness systems in the local Universe that were not detected so far by means of resolved stellar populations or HI surveys. In the Local Group, low-resolution deep images of the Magellanic Clouds with telephoto lenses have found some shell-like features, interpreted as imprints of a recent LMC-SMC interaction. In this review, I discuss these highlights and other important results obtained so far in this new type of collaboration between high-class astrophotographers and professional astronomers in the research topic of galaxy formation and evolution.
