Where is Ophiuchus?

Ophiuchus is directly below Ursa major and Grandfather, that is, in the south, you can see the slender Ophiuchus. Ophiuchus extends from east to west to the lower part of the M44 cluster in Cancer (South), winding up to 100 degrees and about 7 palms wide. It is called the longest constellation in the whole day together with the wave constellation in winter.

Ophiuchus, though extremely long, does not have a dazzling star. There is only one second-class bright star that emits red light (that is, Ophiuchus alpha constellation), and the heart of Ophiuchus is this constellation. Because there are no other bright stars around the stars, Arabs are vividly called "loners".

Part of Ophiuchus can be seen all over the world, but its long body is difficult to recognize because there are many fourth-and fifth-class stars. The most obvious feature is the six-star group of its snake head, which is located in the east of Nanhesan 15. For the observation of middle and high latitudes in the north, Ophiuchus hangs low on the horizon and needs ideal observation conditions.
