Double Double Epsilon Lyrae

Only Double (Double Double  Epsilon Lyrae)

About 1,2° east from Vega it's possible to observe a double star with low magnification. This is epsilon Lyrae and is separated by 208 arc seconds. Compare this with a separation of 720 arc seconds of Alcor & Mizar in the constellation Ursa Major.
When viewing with larger magnification both stars have a compagnon. They are separated by respectively 2,3 arc seconds and 2,4 arc seconds.

Visual I was able to see the Double Double using reflector TAL200K with 12mm. However, my pictures did not cover the Double Double; both using the TAL200 aswell as the TLAPO80/480 f/6.
