My largest project to date. I'm not happy with the result, but I can't bring myself to throw it away—after all, I spent more than one night capturing it. I had to discard a lot of frames... On top of that, I had to crop the image due to stacking artifacts. I plan to re-shoot it a bit later, add Oxygen, Sulfur, and a bit more Hydrogen, and do it without cropping. For now, let this version stay as a reminder of my "baptism by fire," so to speak. A challenging object.
