 		 The encroaching fog made this a challenge. Its location was easily found in binoculars but only found in the findersope with averted vision. A star hop from Herc92 or 100 is useful. Despite the 
details( reviewed afterwards) in Paolo's listing I found an almost equal magnitude companion just touching this star at X72 but separated at 144. A wide and very faint companion was nearby. 

Ambience: The night started out cloudy and suddenly all cleared. By the time I had set up fog started to roll in and the viewing area took on an eerie, shadowy appearance. After ten minutes of viewing I decided to pack up as Hercules slowly faded. My cat tapped my window at 5.30a.m. the next morning and my reward for letting her in was the stunning picture of Saturn, Jupiter and the Pleiades in a close grouping in the pre-dawn sky.
