Zeta Lyrae – Double Star

I found myself wandering around with the telescope in a double star mood, it has been a long time since I viewed many of these and the first time imaging them. This is the binary system Zeta Lyrae, also referred to as Zeta 1 Lyrae and Zeta 2 Lyrae. The distance to this system is roughly 150 light years and their magnitudes are 4.3 and 5.7 respectively.
