This image was created by median combining 7 x 90 second unfiltered images taken with a Takahashi Epsilon 250 with SBIG ST-8XE CCD. The image has been cut down to be 20 x 20 arc minutes in size.
Messier 4 (NGC 6121) lies at a distance of about 7,200 light years and as such is one of the nearest globular clusters. Messier was the first person to resolve it into stars and M4 was the only globular cluster where he succeeded in doing this. M4 is heavily obscured by interstellar dust that both reddens and dims the light we see.
