Sh 2-230: A HII-Region Comprising Many More Deep-Sky Object

Sh 2-230 is a very faint and extended emission nebula that encompasses a number of other a number of other Sharpless objects in the heart of Auriga. The Sharpless 2 catalogue (Sh 2) is a list of 312 HII (Hydrogen Emission Nebula) regions with the intention, to form a complete list of these objects north of declination δ = -27°. The first edition of the catalogue from 1953 was labelled Sharpless 1 (Sh 1).


Sharpless 2-230 comprising Sh 2-234 (IC 417), Sh 2-236 (IC 410, NGC 1893), Sh 2-229 (IC 405), M38 (NGC 1912) and NGC 1907

M 42 The Orion Nebula and Neighbors

The celestial region shown in the image comprises the surroundings of the Large Orion Nebula. Most of the objects visible in the photographs are located in the Orion arm of the Milky Way, as is our home solar system.

Soul Nebula IC 1848 and Heart Nebula IC 1805

The Soul Nebula (IC 1848, Sharpless 2-199, LBN 667) is an emission nebula located in constellation Cassiopeia. Several small open clusters are embedded in the nebula. This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".

The Heart Nebula (IC 1805, Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the milky way (as the Soul Nebula in the constellation Cassiopeia).

The Iris Nebula NGC 7023

The Iris nebula is a bright reflecion nebula in the constellation Cepheus. It's appearance is caused by the very hot star HD 200775 in it's centre whose light is partly reflected and partly absorbed by surrounding dust clouds. As can be seen from the labeled image, the dust cloud itself can be found in Lynd's cataologue of dark nebulae as entry LDN 1174. The reflection nebula shines at magnitude +6.8. It lies 1,300 light-years away and is six light-years across

NGC 2237 The Rosette Nebula

The rosette nebula NGC 2237 is a H-II emission region in the constellation monoceros (unicorn). Its distance to our solar system was measured to be roughly 5.200 light years and its diameter to about 130 light years. A mass estimate yields approximately 10.000 solar masses.
