Thanks for the info
I wasn't aware of LEDA 2024204 when observing arround M57. Actually I was going for IC 1296 but when I was looking arround something distracted my averted vision. It was probably the 5th star but I was sure then that it may be a galaxy. Found it on DSS and yes it was a galaxy close to the star. I may have see it or not. I have to try again. Someone with a bigger scope may tell as how faint it actually looks.
