NGC1786
👁 A cluster of stars in space. It’s bright in the centre, where the stars are densely packed together in the cluster’s core, and grows dimmer and more diffuse out to the edges, as the stars give way to the dark background of space. A few orange stars are spread across the cluster, but most are pale, bluish-white points of light. Three large stars with cross-shaped spikes around them lie between us and the cluster.
