Comment
It's up-side-down, north is to the bottom.
One of the bright spiral
galaxies visible in the north sky is M63, the Sunflower Galaxy. M63,
also catalogued as NGC 5055, can be found with a small telescope in
the constellation of Canes Venaciti.
M63 interacts
gravitationally with M51 (the Whirlpool Galaxy) and several smaller
galaxies. Light takes about 35 million years to reach us from M63.
