• Most of these go against the typical Wikipedia convention to disambiguate articles by using parentheses after the article name, and discussion on WikiProject Astronomical objects has come to the view that the format should be Messier #. Many of the destination pages are redirects with more than one item in the history. Chaos syndrome 20:38, 25 July 2006 (UTC)

Not the first extragalactic globular cluster

As early as 1932, Edwin Hubble discovered 140 extragalactic globular clusters around the Andromeda Galaxy. I think the author meant that M54 is the first former 'Galactic Globular Cluster' correctly recognized to belong to a dwarf galaxy orbiting our Galaxy. --Diamonddavej (talk) 01:34, 19 June 2011 (UTC)

Several globular clusters in the Large and Small Magnellic Clouds as well as in the Fornax Dwarf Spheroidal were discovered in the 19th century are in the NGC catalogue. I don't know when they first associated with their host galaxies though but at least before the 1950s (e.g. Gascoigne & Kron 1952). Korandder (talk) 13:52, 15 October 2015 (UTC)

Radius

What is the source of the radius quoted in the info box? Also what sort of radius is it? Core, half-light, tidal or some other one? Korandder (talk) 13:48, 15 October 2015 (UTC)

Numbers dont add up

Figures on the SagDEG article place it at 70,000 LY from Earth, with a diameter of 10,000 LY, with "M54 apparently at its core". Yet this article here M54 gives a distance on 87,000 LY, which would put it well beyond the core.

This comment also made on the SagDEG article. — Preceding unsigned comment added by 2001:8003:E448:D401:E8BE:3E5F:C4C2:ACB9 (talk) 03:52, 7 October 2019 (UTC)
