What to look for
Look for the warm central glow and the irregular, patchy spiral structure that gives M63 its Sunflower nickname.
Capture lesson: A few aberrations remain visible in this image, including asymmetric spikes and streaks around the brighter stars. There are a few other minor issues I have noted, so this will not be the final image of the Sunflower Galaxy. Since it is one of the first images from my EdgeHD 8 while I work through these issues, I still wanted to share it.
