|Beta Herculis, Kornephoros, is a yellow giant (twenty times the Sun's radius) whose name, meaning 'club-bearer', refers to the weapon it wields as it kills the serpent. It is actually slightly brighter than alpha Her, 2.78 to 3.03, but with the combined magnitude of alpha's companion it too has an apparent magnitude of 2.78.
With the naked eye, from beta Herculis you can move eastward to delta; midway is a delightful telescopic binary 56 Herculis, (Struve 2110) an orange primary and blue companion: 6.1, 10.8; 92º, 18.1".
One and a half binocular fields east brings you to delta Herculis.
Delta Herculis is an optical double with a striking colour contrast, generally described as a whitish-yellow or orangey primary and a bluish-green or perhaps purple companion: 3.1, 8.3; 289º, 12.4".
Two binocular fields north bring you to pi Herculis. Click on pi on the map.
