Anyway, the spiral arms and dust in this galaxy are obvious.

Galaxy M81
While experimenting with automatic tracking and stacking, I took this image of galaxy M81. The polar alignment of the telescope was poor, hence the common part of all sub-images was relatively small. So I ended up with a galaxy not even fitting in the final image.
