Ra 02h 51m 36.24s Dec +60° 26′ 53.9"



Image is in HST-palette, (HST=Hubble Space Telescope)

from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.

This is a final version of IC 1848. I shot more H-alpha, 15 x 20min., since the first set was ruined by the orthogonality problem between the optical path and CCD. Now all stars are pinpoints at a whole field of view.



Soul Nebula, (Sh2-199, LBN 667) is an emission nebula in constellation Cassiopeia. IC 1848 is a cluster inside Soul Nebula. Distance is about 7.500 light years. This complex is a Eastern neighbor of IC 1805, the "Heart Nebula" and they are often mentioned together as Heart and Soul. Both nebulae can be seen in this older image: http://astroanarchy.blogspot.com/2011/01/two-reprocessed-objects-rosette-and.html
