Summer Triangle in the Trees

From the photographer: “In autumn on the northern hemisphere, the summer constellations Lyra, Cygnus and Aquila reach to a position near the north-western horizon. Waiting for a special moment, I saw the bright stars Albireo, Vega and Altair appeared in the high trees. Above Deneb you can realize the North America Nebula.
