Soul Nebula, up close & personal



In this blog post of mine, I'm showing a collection of the Soul Nebula images. Some of them are shot in previous years and some at this Autumn season. All images are reprocessed since I have now a better technique.

IC 1848, the "Soul Nebula"
Ra 02h 51m 36.24s Dec +60° 26′ 53.9"



Image is in mapped colors, from the emission of ionized elements,
 R=Sulfur, G=Hydrogen and B=Oxygen.



Soul nebula in wider field image

In this wide field image, the Soul Nebula is shown with its neighbor, the Heart nebula.
Image is shot with the Canon EF 200mm f1.8 lens, Baader narrowband filters and the QHY9 cooled astronomical camera. 


Info

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.

Orientation

The previous closeups are marked in this image as a white rectangles.



A collection of images in visual spectrum
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
