IC1805 Soul Nebula 23-Oct-24

Target: IC1848 Soul Nebula

Dual narrowband filter image of the Soul nebula. It was processed using the Pixinsight Narrowband Normalization process HOO pallet that I find allows the Oiii to come out. This does change the Ha Reds to a shade that I then correct in PS using selective colors. IC1848 was nicknamed the Soul Nebula likely due to the neighboring Heart Nebula IC1805.
