The 79th of the Connoissance des Temps is a cluster of stars of a globular construction, and certainly extremely rich. Towards the centre the stars are extremely compressed, and even a good way from it. 300 power shows the stars of it with difficulty. 1806, large 10 feet telescope. It is bright, of moderate condensed type and about 2.5' across with outliers extending considerably wider.
Large apertures show gleaming points right to the centre.
A 12-inch or larger will show the object richly resolved into a tight ball of faint stars. A string of six stars is just E of center and a long string passes through the core. The outer halo is well resolved in excellent conditions. Well resolved, with about 12 stars in the compressed central section and another 50 stars in the outer portions. All against a very grainy backround.
