Exploring Lyra

Conditions:
Clear, steady seeing, sky along the horizon very bright with light pollution, no moon

Targets Observed:
Epsilon, Delta and Zeta Lyrae and M57

Notes
Nice introduction to one of my favourite constellations.

Set a task of finding some double stars tonight and started working through the Astronomical League's list of the Top 100 double stars. Began with the famous double double Epsilon Lyrae, which was the first double star I ever found on my own with binoculars. Tonight I saw the doubles and noticed that they seemed aligned perpendicular to one another. Not really clear separation, but enough to see the shape.

Delta Epsilon was interesting, and like Zeta is clear to see, and one star much dimmer than the other.

looked for M57 and couldn't quite believe it when I saw it. Looked like the scope was out of focus. At highest powers, definitely saw structure in the nebula, although not very clear. This nebula is lit by a star shining at 15.9 magnitude, which is dying.

Tried for M56 but with no luck. I'll get more detailed charts for that globular cluster.
