Although a conspicuous cluster, even in the smallest telescopes or opera glasses, M25 has only obtained an IC number. This is because due to unknown reason, John Herschel did not include it in his General Catalog, although it had been observed by de Chéseaux in 1745-46, Charles Messier in 1764 (added to his catalog on June 20, 1764), added to the 1777 catalog of Johann Elert Bode, observed by William Herschel (1783) and Admiral Smyth (1836), and by Reverend Thomas William Webb (1859). According to Kenneth Glyn Jones, it was finally rediscovered by Julius Schmidt (1825-84) in 1866, but the present author [hf] could not yet verify this presumed rediscovery, despite studies e.g. of the Astronomische Nachrichten of that years. Eventually, M25 was added to the second Index Catalog by J.L.E. Dreyer in 1908, based on photographic observations and using a position obtained by Solon Irving Bailey (1854-1931), published in Bailey (1908).
