Globular Cluster NGC 6749
This cluster of stars was discovered by John Herschel on 15 July 1827. He cataloged it as h 2029 (GC 4466). He noted: «A cluster of loose small stars of various magnitudes; fills the field.»  In his «General Catalogue» appeared in 1864 he described GC 4466 as «Cluster; large; little compressed; stars large & small.»  John L. E. Dreyer added it as NGC 6749 in 1888. 
The cluster is also known as Berkeley 42 and was first misclassified as open star cluster of classification I3r consisting of «very faint stars». 
NGC 6749 is a loose globular cluster. Its blue horizontal branch indicates that the stars are metal-poor, which is typical for globular clusters. Its distance from the Sun is estimated to 7.3 ± 0.9 kpc. It is a halo globular cluster close to the disc plane.
