Probably the most observed multiple star system, located in an easy position in Lyra near the bright star Vega. The double can be split even with better binoculars, however the real magic happens with larger telescopes as under good conditions, they will split the double into a "double double"! At 71x I was unable to split the pairs, however at 167x and 250x I had success. A very spectacular object, worth giving a try!
