簡介
1774年發表的《星雲星團表》第一版記錄了45個天體，編號由M1到M45。1780年增加至M70。翌年發表的《星雲星團表》最終版共收集了103個天體至M103。現時梅西耶天體有110個，M104至M110是後人把由梅西耶及他朋友梅襄（Pierre Méchain）所發現而未被編入《星雲星團表》的天體所加入的。
不過後人發現，M40是大熊座中的一對雙星，M73（NGC6994）是寶瓶座中的一組小星群，而M102據說於1781年被梅襄“發現”，1783年他又否認，在他給柏林的貝努里的通信中說那是M101的觀測結果的重複記錄，所以實際上梅西耶等人觀測到的深空天體為107個。M40、M73、M102常被稱為“遺失的梅西耶天體”。
