The early part of this session was finding a few objects for Explore the Moon (Binocular) (June 25, 2017)
At some point in the later portion of the observing session, I noted how easily the Summer Triangle could be seen - Deneb in Cygnus, Altair in Aquila and Vega in Lyra. After finding the stars of the Triangle, I then looked at their related constellations briefly.
I was able to locate the Keystone of Hercules using the Corona Borealis as the pointer. Looking between η and ζ Herculis, I found the small grey fuzzy known as M13, a.k.a. the Hercules Cluster. Couldn't make out the star field definition.
Could only find Polaris, Pherkad and Kochab in Ursa Minor. Could not find the other stars either naked eye or with my binoculars.
From Albireo, I went 1/2 FOV and found the Coathanger. All 10 stars of the asterism were easily found.
In Cygnus, I followed the stars from Deneb down to Albireo. Although I could find the two stars of Albireo in my binoculars, I couldn't distinguish the blue and yellow.
Jupiter was easily identified. I found it basically at the same declination as Arcturus. It was quite bright! Didn't make note of the location of its 4 moons.
