| Description | This was an enjoyable capture, and after 40m of integration I shut things down thinking I'd done a great job. However, I hadn't focused on the peculiarity of this galaxy, which was, "Galaxies with narrow filaments". Turns out I had been fooled by the bright galactic center and disk, not recognizing that the filaments were MUCH less bright. This led me to some "heroic" processing in Affinity Photo of the saved .png image, which "just" exposes the roots of the filaments and hints at their directionality. In a perfect world I would go back and capture another 40 minutes.... |
