IC 1848 & Others (2025)

This is my latest version of the very large emission nebula located approximately 6500 light-years away in the constellation of Cassiopeia. The designation of IC 1848 actually refers to the open star cluster in the blue portion of the image. The stellar winds of stars in the open cluster(s) are responsible for scalping out openings within the gas and dust. This process leaves behind the sharp edges and dense pillars of star forming regions that point inwards towards the star cluster(s). For some reason the entire nebular complex is nicknamed the Soul Nebula, however, my image only shows one side and consists of LBN 670, LBN 667, LBN 672, and LBN 673.

My favorites are LBN 670 in the upper right and LBN 673 in the bottom center. Each of these regions are about ten light-years long and show sharp details. Also, I did use the relatively new Multiscale Adaptive Stretch (MAS) in PixInsight and worked really well. It is pretty simple and you can adjust elements using easy to use sliders - might want to check it out. Lastly, this also happens to be the last image where all the data I collected was from 2025.
