IC5070 Pelican Nebula (Rev. 1)

Der Pelikannebel (auch bekannt als IC 5070 und IC 5067) ist eine H II-Region, die mit dem Nordamerikanebel im Sternbild Cygnus assoziiert ist. Die gasförmigen Verwerfungen dieses Emissionsnebels ähneln einem Pelikan, was ihm seinen Namen einbrachte.

• SH2-155 Cave Nebula (Rev. 1)
• SH2-155 Cave Nebula (Rev. 2)

Sh2-155 (auch Caldwell 9, Sharpless 155 oder S155 genannt) ist ein diffuser Nebel im Sternbild Cepheus, der zu einem größeren Nebelkomplex gehört, der Emissions-, Reflexions- und Dunkelnebel enthält. Er ist allgemein als Höhlennebel bekannt, obwohl dieser Name früher auf Ced 201, einen anderen Nebel im Sternbild Cepheus, angewandt wurde.

• NGC2239 Rosette Nebula (Rev. 1)
• NGC2239 Rosette Nebula (Rev. 2)

The Rosette Nebula (also known as Caldwell 49) is a H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter.

• NGC7023 Iris Nebula (Rev. 1)

The Iris Nebula (also known as NGC 7023 and Caldwell 4) is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487.

• NGC2359 Thor’s Helmet (Rev. 1)

NGC 2359 (also known as Thor’s Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 15.000 light-years away and 30 light-years in size. The central star is the Wolf-Rayet Stern WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution.

• M51 Whirlpool Galaxy (Rev. 1)

Die Whirlpool-Galaxie, auch bekannt als Messier 51a (M51a) oder NGC 5194, ist eine wechselwirkende Spiralgalaxie mit einem aktiven galaktischen Kern vom Typ Seyfert 2. Sie befindet sich im Sternbild Jagdhunde und war die erste Galaxie, die als Spiralgalaxie klassifiziert wurde. Sie ist etwa 31 Millionen Lichtjahre (9,5 Mpc) von der Erde entfernt und hat einen Durchmesser von 76.900 ly (23.580 pc).

• IC1396 Elephant’s Trunk Nebula (Rev. 1)

The Elephant’s Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2.400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant’s Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim.

• NGC2170 Angel Nebula (Rev. 1)

Reflecting the light of nearby hot stars, NGC2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. This object is considered a massive, star-forming molecular cloud in the constellation Monoceros.

• M101 Pinwheel Galaxy mit SN2023ixf (Rev. 1)

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.

• WR134 (Rev.1)
• WR134 (Rev.2)

WR 134 is a variable Wolf-Rayet star located around 6.000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63.000K it is 400.000 times as luminous as the Sun.

• SH2-174 – the “Valentine Rose” (Rev.1)

Sh2-174 is a planetary nebula in the constellation Cepheus.

It is one of the most northerly planetary nebulae in the nightsky. This makes it almost exclusively observable for the Northern Hemisphere.
