IC1848 – Soul Nebula (2015/11/06)

Stars are forming in the Soul of the Queen of Aethopia. More specifically, a large star forming region called the Soul Nebula can be found in the direction of theconstellation Cassiopeia, who Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river. The Soul Nebula houses several openclusters of stars, a large radio source known as W5, and huge evacuated bubbles formed by the winds of young massive stars. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805). The featured image appears mostly red due to the emission of a specific color of light emitted by excited hydrogen gas.” (from APOD)

The weather in Bay Area in Nov. is usually not great as the rain season starts, but this year it had two great weekends before El Nino hit us. I took 2 panel mosaic Ha in 11/06, and 2 panel mosaic O3 in 11/13. The final bi-color image has pleasant yellow color, which is very different from true RGB or NB images.
