On this page I collect my observations of the globular star cluster M 4 (NGC 6121) in the constellation Scorpius.
The globular star cluster M 4 in the constellation Scorpius is the only globular star cluster that Messier was able to resolve in his small telescopes. From Central Europe, it is the most resolvable globular cluster, but difficult to observe because it is located far south.
Size: 12' (Stoyan)
Distance: 7,200 light years (Stoyan)
Rating: *** (Stoyan)
M 4 is located in constellation Scorpius (M 80 is to the right of M 4). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
Find: M 4 is located to the right and below of the large and yellow star Antares in constellation Scorpius (see maps above and below). It is even closer to the star sigma Scorpius (the Western Al Niyat), below which it is located.
Identify: If you have found the star Antares, which is large and yellow, you will also be able to identify M 4. (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
