The Summer Triangle And Northern Cross
 

The Summer Triangle shown top centre of the image. Title is a little misleading as it can be seen Fully In March.

​

The Triangle is formed by three of the brightest stars in the summer sky. On the west corner of the triangle is Vega, the 5th brightest star in the night sky. On the south corner is the first magnitude star Altair in the constellation Aquila. At the northeast corner is the star Deneb in Cygnus.

​

The Summer Triangle is almost 40 degrees in diameter, and it intersects the constellations Lyra, Cygnus and Aquila. Look for this large asterism in the evening sky during the summer and early Autumn

​The Northern Cross is a prominent asterism, or star pattern lying within the The Summer Triangle. Also lies within the constellation Cygnus (the Swan), forming a cross-shaped figure in the northern sky comprising of Deneb, Sadr, Gienah, Al Fawaris and the wonderful and very popular double Star Albireo appearing Indigo and gold.
