The first stunning summer deep-sky objects is the rather large summer Milky Way in Sagittarius, Scutum, Ophiuchus and Aquila. It is a particularly awe-inspiring sight, especially from dark sky sites. To get a good view of it from the UK it is best to travel to a site with a very clear southern horizon.
Nestled within the Milky Way in the constellation of Sagittarius, just above the spout of the Teapot asterism, you'll find the Lagoon Nebula (M8). It's a great object to look at with binoculars and even better in a small telescope.
About 7° to the East of the Lagoon Nebula lies the magnificent globular cluster of M22. You shouldn't have too much trouble picking it out using binoculars, but for a real WOW, try observing it with a large telescope to see it sitting against the glittering starfields of the Galaxy.
There are several other striking summer nebulae in this region of the sky. The Eagle Nebula (M16) and M17 are excellent targets for 6 to 8-inch reflectors; located in Serpens and Sagittarius respectively. Not far away in Scutum lies the Wild Duck Cluster, M11.
Summer Meteor Showers
Summer is a quiet time for meteor showers, the only one of note is the Perseids which are active from July 13 to August 26, reaching a strong maximum on August 11th - 13th.
