CYGNUS
Cygnus, the celestial Swan, flies toward lower right and to the horizon, great Deneb, seen toward the upper left, marking its tail. Albireo, down and to the right, marks the Swan's head, Sadr, just up and to the left of center, its breast.

Cygnus occupies the overhead region of the summer Milky Way. This areafull of clusters and nebulae, so it might have been difficult to pick up the most favourite target if Cygnus was not a home to the Veil supernova remnant as well.

Cygnus, the swan:
Cygnus is one of the largest and easiest to find constellations in the night sky. It is also one of the few constellations that actually resembles its namesake.
Cygnus X-1, also known as V1357 Cyg and HD 226868, was the first black hole candidate ever discovered.

Cygnus is situated in the Milky Way. Its brightest stars mark the Northern Cross. Cygnus, with the bright star Deneb in the swan's tail, appears high in the summer sky.

At the root of its tail lies the bright star Deneb, here labelled simply Alpha.
Because Cygnus is in the Milky Way, it is rich in Galactic objects that are visible in binoculars and modest telesecopes, notable are the enormous North America Nebula (NCG 7000) and the faint shreds of the Veil nebula, ...
Cygnus X-1 - This is a very strong x-ray source. However, when you observe it with a regular telescope you see an O type star (named HDE 226868 - isn't that romantic?). The O star is not a source for x-rays, so where are those coming from?
Cygnus X-1
(a) A black hole candidate in the constellation Cygnus and a source of x-rays.
(b) An X-ray source about 2.5 kpc distant (period 5.5998 days, e 0.06, i 27°).

Cygnus X-1 is the longest known of the black hole candidates. It is a highly variable and irregular source with X-ray emission that flickers in hundredths of a second.
Cygnus X-1 is the oldest known case of a black hole candidate. It is a dark companion of a type O star. Its lower mass limit is 7 solar masses and it emits X-rays. Everything indicates it is possibly a black hole.
