  This is a multi-panel mosaic of Sharpless 2-199 also known as LBN 667, or IC1848, and commonly called the 'Soul', 'Fetus' or 'Baby' nebula.
Located in Cassiopeia, this nebula consists of two large star factories where radiation, dust and solar winds form the bubble shapes plus the formations of IC1871, LBN670 & LBN673. Located in the left nebula are open star clusters (Collinder Catalog) CR33 & CR34 and the right nebula, CR32. The right side bubble is also known as IC1848.

  The 9 mosaic panels were laid out using Sequence Generator Pro's mosaic planner and utilized a 10% overlap. The newly acquired software tool, Astro Pixel Processor (APP), was used to calibrate, normalize, register and integrate the 9 panels and assemble to create a seamless image. APP does an excellent job with normalizing and blending mosaic seam backgrounds which eliminates extra manual work associated with that process. Though APP can do post color processing, I found Photoshop to be my tool of choice for that part due to the powerful masks that PS provides.
