Description:
At more 4° of Enif NW. At the beginning, I have difficulty it of locating but I succeeded in finding it after a few minutes. These difficulties come from the high degree of concentration of this cluster, which seemed to be a star at the time of research. This cluster shows a strong concentration with the binoculars. It's visible in direct vision and the center appears, at this time, also shining like a star. In averted vision, a halo was visible all around the center. The dimension of this halo was not very large, another proof of the high degree of concentration.
