梅西耶星表（統一比例尺）
Messier Catalog at Uniform Scale
發表日期：2026-05-14
夜空中有哪些最有趣的天體？只要備有一副好的雙筒望遠鏡或一臺小型望遠鏡，如果你生活在北半球，就可以尋找梅西耶星表中那些廣為人知的天體。其中大部分（但並非全部）在南半球也能觀測到。 配圖展示了星表中全部 110 個天體，採用統一比例尺——即相同的放大倍率。查爾斯·梅西耶於 18 世紀編制了這份星表。他對彗星頗有研究，該星表最初是他在觀測或搜尋彗星時，為避免誤判而列出的已知彗星狀“需避開天體”的清單。 該星表中的深空天體包括一顆超新星遺蹟（蟹狀星雲，M 1 ）、其他星系（如仙女座星系，M 31 ）、星雲（例如獵戶座大星雲，M 42 ，一個恆星形成區）以及星團（如昴星團，M 45 ，一個明亮的年輕疏散星團）。
原文：What are some of the most interesting astronomical objects you can see in the night sky? Armed with a good pair of binoculars or a small telescope, if you live in the Northern Hemisphere, you can look for the very popular objects in the Messier Catalog. Most of them, but not all, are also visible from the southern half of the Earth. The featured image shows all 110 objects in the catalog at uniform scale -- the same magnification. Charles Messier created the catalog in the 18th century. He was interested in comets, and his catalog was a list of known comet-like "objects to avoid" in the sky when observing or hunting for comets. The deep sky objects in the catalog include a supernova remnant (the Crab Nebula, M1), other galaxies (such as Andromeda, M31), nebulae (e.g. the Orion Nebula, M42, a star-forming region) and stellar clusters (such as the Pleiades, M45, a bright young open cluster).
