This is a globular cluster in Sagitta. It is an interesting object which sits on the boundary of globular cluster and open cluster.
At 110x it shows a triangular shape. It is fairly bright but there is no clear concentration. Scattered bright stars are resolved with closed packed faint stars between them. However, the level of concentration is low and can be categorized as an open cluster.
In the northeast there are scattered stars and they seem to be members of this cluster. There is a small line of stars in the north and at the center there is a conspicuous bright star. Even at 190x it is not completely resolved and looks triangular.
