The rightmost of the three bright stars along the bottom edge is Beta Lyrae, an eclipsing binary system with what seems to me to be a very short period — about 13 days. The next minimum brightness is on June 21, so it’s on the dimmer side at this moment.
I think the smaller of the pair is kissing at the upper left edge. Weather and attention span permitting, I will take another picture in a few days to see if the position has changed. I will be absolutely amazed if my tiny telescope can actually show two stars orbiting each other over a span of a few days!
Further research says: Nope. Wikipedia has a great article about Beta Lyrae, and the eclipsing binary cannot be resolved by optical telescopes. However, there are separable companions of Beta Lyrae that are undoubtedly captured above. Unfortunately, I can’t identify them…
