The famous Double-Double, at first glance this appears to be a wide 3.5' double star, upon closer inspection each of the two can be further split into a pair of pairs. The southern CD pair (also ε2 Lyr or 5 Lyr) is easier to split despite being slightly closer at 2.4" as both stars are well matched at 5.23 and 5.35 magnitude, the northern AB pair (also ε1 Lyr or 4 Lyr) somewhat harder to split requiring good conditions and decent optics due to the fainter magnitude of εLyr B at 6.06 just over a full magnitude fainter than εLyr A at 4.99, the pair is found 1°40' northeast of Vega
