M33, aka NGC598,
aka the Pinwheel
Galaxy, is part of the
local group of galaxies
that includes M31. The
Pinwheel covers a lot
of sky, about the size
of 2 full moons, but is
hard to see in amateur
telescopes because of
its low surface
brightness. Note the
large red emission
nebula within the
galaxy at about 7
o'clock, aka NGC604.
