Sgr - Sagittarius the Archer

Between Cygnus and Sagittarius, with Altair (its brightest star) making the south end of the Summer Triangle (along with Deneb of Cygnus and Vega of Lyra). As the night sky changes, Aquila the Eagle and Cygnus the Swan swing slowly westward across the sky towards the horizon. The Eagle sets tail first, followed closely by the Swan, who dives beak first below the western horizon.

Between Sagittarius and Aquarius. Dim stars; look for a laughing mouth.

One needs a telescopium to see Microscopium, for it contains no star brighter than 4.6. 

Between Scorpius and Hercules.

Look for teapot pattern to the east of Scorpius, complete with handle, lid, and spout. Tea pouring from the spout would indicate the direction of the center of Milky Way, and the entire constellation is rich with many stars. Try binoculars in the area where clusters gather like steam rising from the teapot.

Centaur, half-man and half-horse, shooting an arrow. If you cannot see a creature half-man and half-horse in these stars, then try looking for a teapot. Four stars make the pot... Two stars form a handle... One star is a lid... And the tip of the bowman’s arrow makes a spout.

East of Virgo along the ecliptic the constellation Scorpius creeps above the treetops, with his menacing tail below, and stinger above. Continue eastward along the ecliptic to the next constellation, Sagittarius the Archer.

Located within the Milky Way.

Located in the hands of Ophiuchus, Serpens is the only constellation divided into two parts: Serpens Caput (=head) and Serpens Cauda (=tail), with Ophiuchus between them.
