The Cygnus Fairy Ring as viewed with a 10-inch f/4.5 reflector on August 13, 2015.  Transparency was poor due to very high humidity but seeing was excellent.

The asterism was easy to locate and see using a 32mm eyepiece @ 36x with a 1.8º FOV.  The most recognizable member of the group was double star H1470 with the primary being a ruddy or rust color.

When increasing the magnification, using a 20mm eyepiece @ 57x with a 1.1º FOV, I could see at least eight or more separate pairs of double stars making a circle.   

While taking a bicycle ride just the other day (August 6th 2020) I came across a yard with a true 360º Fairy Ring.  I just had to stop and take a photo.   Roger Ivester
