Although more easily found using Serpens Caput, I went down 2 FOVs plus a bit more from Arcturus to find it. Other than bright the bright centre, I couldn't make out any significantly bright individual stars in this very tight cluster. I saw 4 stars below M5 that I was able to identify with SkySafariPro.
