| If you want to see the nebulosity surrounding the stars in the cluster, though, you'll need at least a 12-inch telescope. |
| By going back as far as possible, we thus arrive at a nebulosity so diffused that its existence could hardly be suspected. |
| Prof. Barnard adds that the nebulosity is easily visible in a 12-inch telescope. |
| The nebulosity of the ten-foot can be resolved into stars by the twenty-foot, and so on. |
| Were the nebulae really all star systems at vast distances from Earth, or were there also regions of true nebulosity, clouds of luminous fluid? |
| At the top, the sight is one of most beautiful in the world provided that the nebulosity is nil. |
