Soul Nebula (SOH)

The Soul Nebula is an emission nebula in Cassiopeia. It almost certainly gets its name because of its proximity to the Heart Nebula in the sky and not due to any chance resemblance to whatever a “soul” looks like. For some reason my image tends to look like a baby rhinoceros to me. Your mileage may, of course, vary.

This is 9,7 hours of data captured over five nights in February and March 2020. I decided to do an SOH image rather than more conventional Hubble palette. In this image, sulphur is mapped to red, oxygen to blue and hydrogen to blue. This made for a very different color scheme but I liked the vibrant blue with the purple edging the nebula.

You can find the image on astrobin.
