We have comparatively many opportunities to go out to highlands and mountains in summer, and can appreciate clear and beautiful starlit skies occupied by summer constellations. You can see splendid the summer's Milky Way flowing toward the southern horizon, and enjoy uncountable nebulae and star clusters distributed along the Milky Way. Almost all of those objects can be observed only with small binoculars and telescopes, it's most suitable season for night sky-stroll. |
I've added "SPLENDID !" marks in especially magnificent objects. Check those without forgetting ! And you can choose other 4 ways for browsing. Please use your favorite one as the need arises. |
Nebulae & Galaxies in Summer | To Preview of Inner-Galactic Nebulae |
Many splendid diffused and dark nebulae are bathed in the summer's Milky Way.
And especially the field around Sagittarius and Scorpius contains the center of Galaxy, it's extraordinary rich in hydrogen gases. You can enjoy and be fascinated by some naked-eye objects like the Lagoon Nebula (M8), and invisible but unique-shaped H-alpha gases like the North-American Nebula (NGC7000). |

Globular Clusters in Summer | To Preview of Globular Clusters |
You can see really plenty of globular clusters in summer skies, more than 20 globulars have the Messier's numbers. The globular clusters have been born almost same time with the Galaxy itself, and distributed around the Halo region surrounding the central bulge of the Galaxy. You might be needed telescopes to observe almost all of those, several are enjoyed only with binoculars like the Hercules Cluster (M13), M22 in Sagittarius, and so on. |
