NGC 488

M101 

NGC 488 is a face-on spiral galaxy in the constellation Pisces. It is at a distance of about 90 million light-years away from Earth. Its diameter is estimated to be 52,6 Kpc (171.000 ly). The galaxy has a large central bulge, and is considered a prototype galaxy with multiple spiral arms. Its arms are tightly wound. Star forming activity has been traced within the arms. The nucleus of NGC 488 has been found to be chemically decoupled, being twice as metal rich as the central bulge of the galaxy.   (wiki)
We can also see many background (distant, 500-650 MLY) galaxies and e
ven some quasars  are here visible; the most distant (with z=3.82 and light travel time more than 12 billion years) is marked near the upper left corner.
