There're approximately 50 BFS in Wetland Park in afternoon (around 2pm), and I see there're 2 ringed.
It looks likely the value K81 when I use the telescope to see there, but the image quality is limited by my instrument.
Unfortunately the forum does not allow me to upload more photos within the short period, I may try to upload some more photos for this BFS.
