Developing International Strategies Way contracted, some concentrations of material formed in a halo surrounding the core. Stars formed within these huge concentrations of dust and gas, then those stars attracted one another and became the globular clusters. There are just over one hundred globular clusters gliding around the center

However, many objects in the sky are too large to fit into the field of view of a high-power eyepiece. These objects demand a wide field of view to appreciate their beauty and delicate form. (See .)
