Title

SH2-185 Ghost of Cassiopeia

About this image

Following a summer break from astronomy (apart from two eclipses!) the Ghost of Cassiopeia is my first image of the winter season. SH2-185 has been a rewarding but demanding target due to the very bright main star and otherwise faint surrounding nebulosity, which presented very different imaging and processing challenges. In this case I chose to process the data in two ways, each of which highlight different qualities: SHO (shown here) and HOS (see my website).
