Theta Serpentis is a beautiful binary of two white stars: 3.7, 9.3; PA 103º and a separation of 22", clearly resolved in small telescopes and larger binoculars.

The star marks the tip of the serpent's tail, and is found three right-ascension hours east of alpha. (That's to say, if alpha is due south of you, it will take another three hours to pass before theta finally moves directly to the south of you.)

It's easier, and much more fun, to follow the serpent's form, from head to tail, finally coming to theta, which is two binocular fields of view northeast of eta Serpentis or a little more than three fields due east of beta Ophiuchi: binoculars.

You may need some patience to return to your observation post several hours after you've followed the Serpens Caput portion of the constellation, in order to then complete the study of the Serpent. But if you have a small telescope or large binoculars, theta is worth the wait. A truly fine sight.

In the same field, west of theta, is the cluster of about 80 stars known as I.4756, widely dispersed.
