Dark Nebulae
This is a bright emission nebula about 2200 light years away in constellation Cygnus.
It is less imaged than its close neighbors the Northamerica Nebula and the Pelican nebula.
Emission Nebulae
A faint nebula in constellation Cygnus, less frequently imaged.

Emission Nebulae
LBN 321 et al., Kn24, Kn25
Another less imaged region in constellation Cygnus.
Several faint nebulae from Lynds Catalog of Bright Nebulae: LBN 321 and LBN 316 on the right – LBN 284, LBN 290, LBN 296, LBN 299 and LBN 304 on the left side.

Galaxies
Located about 24.3 million light years away from earth in constellation Canes Venatici, M51 and its companion NGC515 are two of the closest neighbors of our Milky Way Galaxy.

Dark Nebulae
A star forming region in Cygnus about 6000 light years from earth.
Not only young stars just being born populate this region but also an already dead star has been identified. Cygnus X-1 can be found not too far from the main nebula in this image. First discovered as the strongest X-ray source in constellation Cygnus (hence its name), it has become the first stellar black hole discovered in our Milky Way galaxy.

Supernova Remnants
Another supernova remnant in constellation Cygnus. The progenitor star exploded about 30000 years ago in distance of about 2600 – 3000 light years and the expelled outer shells of the star span today an area in the sky with an diameter of 8 times the full moon. So what you see here is just the southern part of the nebula.

Dark Nebulae
Several HII regions in constellation Vulpecula about 7000-8000 light years distant.

Dark Nebulae
A wide field in constellation Cygnus with Sh2-101, the Tulip Nebula, as the dominant nebula on the right side. It is a HI region about 6000 light years from earth. Just next to it we can see the companion star of Cygnus-X1, the first confirmed stellar black hole.

Emission Nebulae
A very young star cluster embedded in glowing gas in constellation Serpens, not older than 1 or 2 million years.
