Mu Serpentis is the terminus of the western portion of Serpens. From alpha Serpentis find omega at the bottom of your glasses, then place this star at the top: binoculars.

Now you'll have to starhop across Ophiuchus. Due east of mu Serpentis are two bright stars, found in Ophiuchus. These are delta and epsilon; they represent Ophiuchus' left hand as he holds the serpent: binoculars.

From these two stars move to the southeast about ten degrees; this is zeta Ophiuchi. Now move the same distance in a more east-southeasterly direction. You'll come to eta Ophiuchi and are ready to move into Serpens Cauda, the Serpent's Tail. From eta Ophiuchi move due east one binocular field. You'll encounter a very noticeable stellar triangle: binoculars.
