I'll have to wait until Sunday night, but I'll put this on my list of sky watch targets.

Epsilon Lyrae -- very close by Vega in the sky -- is a famous double-double star -- easily resolved as two stars even in binoculars, each of which can be seen in a small telescope to be a double star system. Oh, and now we know there's a fifth component as well. But wait -- there's more ! There may be several other nearby stars all part of the same (gravitationally bound) system.

Alpha Geminorum is a well known double-triple, but out of sight for now.
